　図２は、図１に示すＩＩ－ＩＩ断面に相当する、反応装置１の平断面図である。図２では、第１伝熱体７を含む部分の反応装置１の構成及び形状が示されている。 FIG. 2 is a plan sectional view of the reactor 1 corresponding to the II-II cross section shown in FIG. FIG. 2 shows the configuration and shape of the reactor 1 in the portion including the first heat transfer body 7.
　反応流路１７は、複数の第１流路２２と、第１合流流路２３とを含む。第１流路２２は、反応流体Ｍに含まれる反応原料に、熱媒体流路３１を流通する熱媒体ＨＣから供給された熱を受容させて、吸熱反応を起こさせる反応領域を含む。第１流路２２は、反応流路１７の本流部に相当し、Ｚ方向の上方を開として、流路断面を矩形とした溝である。本実施形態では、複数の第１流路２２は、それぞれ、Ｙ方向に沿って直線状に延伸し、Ｘ方向に沿って等間隔に並んでいる。第１流路２２の一方の端部は、第１伝熱体７の一方の側面を含む熱交換部３の第１側面６０で開放されている。第１側面６０で開放されている第１流路２２の端部が、反応流体Ｍが導入される第１導入口２０である。第１流路２２の他方の端部は、第１伝熱体７の他方の側面を含む熱交換部３の第２側面６１の側で第１合流流路２３に連通する。なお、図２では、第１流路２２の数を一例として８つとしている。ただし、第１流路２２の数は、特に限定されるものではない。 The reaction flow path 17 includes a plurality of first flow paths 22 and a first confluence flow path 23. The first flow path 22 includes a reaction region in which the reaction raw material contained in the reaction fluid M receives heat supplied from the heat medium HC flowing through the heat medium flow path 31 to cause an endothermic reaction. The first flow path 22 corresponds to the main stream portion of the reaction flow path 17, and is a groove having an open upper part in the Z direction and a rectangular cross section of the flow path. In the present embodiment, each of the plurality of first flow paths 22 extends linearly along the Y direction and is arranged at equal intervals along the X direction. One end of the first flow path 22 is opened by the first side surface 60 of the heat exchange unit 3 including one side surface of the first heat transfer body 7. The end of the first flow path 22 opened on the first side surface 60 is the first introduction port 20 into which the reaction fluid M is introduced. The other end of the first flow path 22 communicates with the first confluence flow path 23 on the side of the second side surface 61 of the heat exchange unit 3 including the other side surface of the first heat transfer body 7. In FIG. 2, the number of the first flow paths 22 is set to 8 as an example. However, the number of the first flow paths 22 is not particularly limited.
　第１伝熱体７は、第１基部１１と、２つの第１側壁１３と、複数の第１中間壁１５と、第１隔壁１９とを含む。第１基部１１は、第１伝熱体７のＸＹ平面全体を網羅する板部である。第１側壁１３は、第１基部１１の一方の主表面上で、第１流路２２の延伸方向に対して垂直方向となるＸ方向の側端にそれぞれ設けられる壁部である。複数の第１中間壁１５は、第１基部１１の一方の主表面上で、２つの第１側壁１３に挟まれ、それぞれ、第１側壁１３に対して平行に並び、かつ、等間隔で設けられる壁部である。また、第１隔壁１９は、第１基部１１の一方の主表面上の第２側面６１側で、第１流路２２の延伸方向に対して垂直方向となるＸ方向に沿って設けられる。ここで、仮に第１流路２２が第２側面６１まで延伸すると、第１流路２２は、熱媒体ＨＣが導入されている第２導入空間Ｓ２に突き当たる。そこで、第１隔壁１９は、複数の第１流路２２を流通してきた生成物Ｐ又は反応流体Ｍの進行方向を変化させて、第１流路２２が第２導入空間Ｓ２に突き当たらないように隔てている。 The first heat transfer body 7 includes a first base portion 11, two first side walls 13, a plurality of first intermediate walls 15, and a first partition wall 19. The first base portion 11 is a plate portion that covers the entire XY plane of the first heat transfer body 7. The first side wall 13 is a wall portion provided on one main surface of the first base portion 11 at a side end in the X direction perpendicular to the stretching direction of the first flow path 22. The plurality of first intermediate walls 15 are sandwiched between two first side walls 13 on one main surface of the first base 11, respectively, arranged parallel to the first side wall 13 and provided at equal intervals. It is a wall part to be sewn. Further, the first partition wall 19 is provided on the second side surface 61 side on one main surface of the first base portion 11 along the X direction which is perpendicular to the stretching direction of the first flow path 22. Here, if the first flow path 22 extends to the second side surface 61, the first flow path 22 abuts on the second introduction space S2 in which the heat medium HC is introduced. Therefore, the first partition wall 19 changes the traveling direction of the product P or the reaction fluid M flowing through the plurality of first flow paths 22 so that the first flow path 22 does not hit the second introduction space S2. It is separated by.
　第１合流流路２３は、Ｚ方向の上方を開として、流路断面を矩形とした溝であり、第１隔壁１９の内側面に沿って直線状に設けられている。第１側壁１３は、生成物Ｐを第１伝熱体７の外部に排出する第１排出口２１を有する。第１排出口２１は、一例として、第３側面６２から外部に向けて開放される。第３側面６２は、熱交換部３における第１側面６０及び第２側面６１とは垂直となるＹＺ平面のうちの一方の側面である。 The first merging flow path 23 is a groove having a rectangular cross section of the flow path with the upper side in the Z direction open, and is provided linearly along the inner side surface of the first partition wall 19. The first side wall 13 has a first discharge port 21 for discharging the product P to the outside of the first heat transfer body 7. As an example, the first discharge port 21 is opened to the outside from the third side surface 62. The third side surface 62 is one side surface of the YZ plane perpendicular to the first side surface 60 and the second side surface 61 in the heat exchange unit 3.
　また、熱交換部３は、第１伝熱体７と第２伝熱体９とを積層して構成されるものであるので、第１伝熱体７の四方の側面は、熱交換部３の四方の側面である第１側面６０、第２側面６１、第３側面６２及び第４側面６３のそれぞれ一部に相当する。 Further, since the heat exchange unit 3 is configured by laminating the first heat transfer body 7 and the second heat transfer body 9, the four side surfaces of the first heat transfer body 7 are the heat exchange unit 3.

　熱媒体流路３１は、複数の第２流路３６と、第２合流流路３７とを含む。第２流路３６を流通する熱媒体ＨＣは、第２伝熱体９に積層されている第１伝熱体７へ熱を供給する。第２流路３６は、熱媒体流路３１の本流部に相当し、Ｚ方向の上方を開として、流路断面を矩形とした溝である。本実施形態では、複数の第２流路３６は、それぞれ、Ｙ方向に沿って直線状に延伸し、Ｘ方向に沿って等間隔に並んでいる。第２流路３６の一方の端部は、第２側面６１で開放されている。第２側面６１で開放されている第２流路３６の端部が、熱媒体ＨＣが導入される第２導入口３０である。第２流路３６の他方の端部は、第１側面６０の側で第２合流流路３７に連通する。なお、図３では、第２流路３６の数を、一例として、第１伝熱体７に形成されている第１流路２２の数又は配置に合わせて８つとしている。ただし、第２流路３６の数は、特に限定されるものではなく、第１伝熱体７に形成されている第１流路２２の数を考慮し、さらに多くてもよい。 The heat medium flow path 31 includes a plurality of second flow paths 36 and a second merging flow path 37. The heat medium HC flowing through the second flow path 36 supplies heat to the first heat transfer body 7 laminated on the second heat transfer body 9. The second flow path 36 corresponds to the main flow portion of the heat medium flow path 31, and is a groove having an open upper part in the Z direction and a rectangular cross section of the flow path. In the present embodiment, each of the plurality of second flow paths 36 extends linearly along the Y direction and is arranged at equal intervals along the X direction. One end of the second flow path 36 is open at the second side surface 61. The end of the second flow path 36 opened on the second side surface 61 is the second introduction port 30 into which the heat medium HC is introduced.

Further, the second partition wall 33 is provided on the first side surface 60 side on one main surface of the second base portion 25 along the X direction which is the direction perpendicular to the stretching direction of the second flow path 36. Here, if the second flow path 36 is extended to the first side surface 60, the second flow path 36 abuts on the first introduction space S1 in which the reaction fluid M is introduced. Therefore, the second partition wall 33 changes the traveling direction of the heat medium HC that has flowed through the plurality of second flow paths 36, and separates the second flow path 36 so as not to hit the first introduction space S1. ..

The second side wall 27 has a second discharge port 35 that discharges the heat medium HC to the outside of the second heat transfer body 9. One end of the second merging flow path 37 communicates with the second discharge port 35. The second discharge port 35 is opened to the outside from the third side surface 62 as an example.

　第３伝熱体３９は、熱交換部３のＺ方向の最上部に設置される蓋体である。第３伝熱体３９の下方に向かって第２伝熱体９と第１伝熱体７とを交互に積層し接合することで、接合体又は積層体としての熱交換部３が形成される。このとき、第１流路２２と、第２流路３６とは、第１基部１１又は第２基部２５を介して並行に隣り合う。熱交換部３の組み立ての際には、各部材間をＴＩＧ（Tungsten Inert Gas）溶接や拡散接合等のような接合方法を利用して固着させることで、各部材間の接触不良に起因する伝熱性の低下等が抑止される。 The third heat transfer body 39 is a lid body installed at the uppermost part of the heat exchange unit 3 in the Z direction. By alternately laminating and joining the second heat transfer body 9 and the first heat transfer body 7 toward the lower side of the third heat transfer body 39, the heat exchange portion 3 as the joint body or the laminated body is formed. .. At this time, the first flow path 22 and the second flow path 36 are adjacent to each other in parallel via the first base portion 11 or the second base portion 25. When assembling the heat exchange unit 3, each member is fixed by using a joining method such as TIG (Tungsten Inert Gas) welding or diffusion joining, so that the contact between the members is poor. The decrease in heat is suppressed.

Specific examples thereof include iron-based alloys such as stainless steel, and heat-resistant alloys such as nickel alloys such as Inconel 625 (registered trademark), Inconel 617 (registered trademark), and Haynes 230 (registered trademark).

However, from the viewpoint of improving the heat exchange performance, it is desirable that the number of heat transfer bodies is large as illustrated in each figure. Further, the number of the first flow path 22 formed in one first heat transfer body 7 and the number of second flow paths 36 formed in one second heat transfer body 9 is not limited. However, it may be appropriately changed in consideration of the design conditions of the heat exchange unit 3, the heat transfer efficiency, and the like. Further, the reaction device 1 may be configured to cover the periphery of the heat exchange unit 3 with a housing or a heat insulating material in order to suppress heat dissipation from the heat exchange unit 3 and suppress heat loss.

The catalyst is supported on the front surface and the back surface of the board 77a, for example. In the example shown in FIG. 13, the holding body 77b is a rod body whose one end is supported by the support portion 44. In this case, the holding body 77b penetrates the central portion of each of the plurality of board bodies 77a, and holds the plurality of board bodies 77a side by side in the stretching direction.

When the tubular structure holds a plurality of discs 77a in this way, the plurality of discs 77a have through holes that allow products to flow between the front surface and the back surface of the disc 77a. You may. Further, the eighth main body portion 77 may have a polygonal board having a polygonal plane shape instead of the board body 77a.
　図１４は、第２触媒体４２の構成例としての第９構成４２ｉを示す図である。第９構成４２ｉは、第９本体部７８と、フランジ部４３と、支持部４４とを備える。ここで、フランジ部４３及び支持部４４は、第１構成４２ａを構成するものと同一であってもよい。 FIG. 14 is a diagram showing a ninth configuration 42i as a configuration example of the second catalyst body 42. The ninth configuration 42i includes a ninth main body portion 78, a flange portion 43, and a support portion 44. Here, the flange portion 43 and the support portion 44 may be the same as those constituting the first configuration 42a.
　第９本体部７８は、第１触媒体４１と同様に、触媒を構造材に担持することにより調製される。第８本体部７７において採用し得る触媒成分や構造材の材質は、第１触媒体４１に採用されるものと同様である。第９本体部７８は、支持部４４からスパイラル状に延伸する板構造体７８ａと、板構造体７８ａを保持する保持体７８ｂとを有する。板構造体７８ａにおいて、延伸方向に対して垂直となる平面上の断面形状は、外径Ｄ１の円である。触媒は、例えば、板構造体７８ａの表面及び裏面に担持される。保持体７８ｂは、例えば、一端が支持部４４に支持され、板構造体７８ａの延伸方向に沿って存在する内周領域を貫通するように延伸する棒体である。板構造体７８ａは、保持体７８ｂから突出する複数の支持棒７８ｃを介して、保持体７８ｂに保持される。 The ninth main body 78 is prepared by supporting a catalyst on a structural material in the same manner as the first catalyst 41. The catalyst components and structural materials that can be used in the eighth main body 77 are the same as those used in the first catalyst 41. The ninth main body portion 78 has a plate structure 78a extending spirally from the support portion 44 and a holding body 78b for holding the plate structure 78a. In the plate structure 78a, the cross-sectional shape on a plane perpendicular to the stretching direction is a circle having an outer diameter D1. The catalyst is supported, for example, on the front surface and the back surface of the plate structure 78a. The holding body 78b is, for example, a rod body whose one end is supported by the support portion 44 and which extends so as to penetrate the inner peripheral region existing along the extending direction of the plate structure 78a. The plate structure 78a is held by the holding body 78b via a plurality of support rods 78c protruding from the holding body 78b.
　さらに、生成物回収部４９は、例えば、Ｚ方向の一方の壁部に、第２触媒体４２を取り付けるための接続部５２を有する。なお、図５では、接続部５２が生成物回収部４９のＺ方向の下部の壁部、すなわち、生成物回収部４９の内壁下面４９ｂ側に設けられている場合を例示している。ここでは、生成物回収部４９に取り付けられる第２触媒体４２が第１構成４２ａである場合を例示する。ただし、第２触媒体４２が第２構成４２ｂ又は第３構成４２ｃであっても同様である。 Further, the product recovery unit 49 has, for example, a connection unit 52 for attaching the second catalyst body 42 to one wall portion in the Z direction. Note that FIG. 5 illustrates a case where the connection portion 52 is provided on the lower wall portion of the product recovery portion 49 in the Z direction, that is, on the inner wall lower surface surface 49b side of the product recovery portion 49. Here, the case where the second catalyst body 42 attached to the product recovery unit 49 has the first configuration 42a is illustrated. However, the same applies even if the second catalyst body 42 has the second configuration 42b or the third configuration 42c.
　接続部５２は、開口部５２ａと、複数のボルト穴５２ｂと、ガスケット溝５２ｃとを有する。開口部５２ａは、生成物回収部４９の内部と外部とで貫通する。開口部５２ａの開口径Ｄ２は、第１本体部７０の外径Ｄ１よりも大きい。したがって、開口部５２ａは、第２触媒体４２の一部である第１本体部７０及び支持部４４を貫通させることができる。複数のボルト穴５２ｂは、フランジ部４３の複数の貫通穴４３ａの位置に対応して設けられ、フランジ部４３を接続部５２に取り付ける際に、貫通穴４３ａを貫通したボルト６５をそれぞれ締結する。ガスケット溝５２ｃは、接続部５２に対してフランジ部４３を密に締結させるために用いられるガスケット６６を取り付ける。なお、接続部５２の全体形状は、フランジ部４３を取り付け可能とする形状であれば、特に限定されるものではない。 The connection portion 52 has an opening 52a, a plurality of bolt holes 52b, and a gasket groove 52c. The opening 52a penetrates inside and outside the product recovery unit 49. The opening diameter D2 of the opening 52a is larger than the outer diameter D1 of the first main body 70. Therefore, the opening 52a can penetrate the first main body 70 and the support 44, which are a part of the second catalyst 42. The plurality of bolt holes 52b are provided corresponding to the positions of the plurality of through holes 43a of the flange portion 43, and when the flange portion 43 is attached to the connection portion 52, the bolts 65 penetrating the through holes 43a are fastened. The gasket groove 52c attaches the gasket 66 used for tightly fastening the flange portion 43 to the connecting portion 52. The overall shape of the connecting portion 52 is not particularly limited as long as it has a shape that allows the flange portion 43 to be attached.
　第２触媒体４２及び接続部５２を上記のような構成とすると、第２触媒体４２が生成物回収部４９に取り付けられた状態では、第１本体部７０は、生成物回収部４９の内壁側面４９ｃに沿った形で配置される。このとき、第１本体部７０は、生成物回収部４９の内壁側面４９ｃ及び内壁上面４９ａには接触していない。 When the second catalyst body 42 and the connecting portion 52 are configured as described above, the first main body portion 70 is the inner wall of the product recovery portion 49 in a state where the second catalyst body 42 is attached to the product recovery portion 49. It is arranged along the side surface 49c. At this time, the first main body portion 70 is not in contact with the inner wall side surface 49c and the inner wall upper surface 49a of the product recovery portion 49.
　ここで、第２触媒体４２の第１回収空間Ｓ３内に収容されている部分に関して、生成物回収部４９の内壁下面４９ｂから、フランジ部４３とは反対側となる第２触媒体４２の先端までの距離をＬ１とする。一方、生成物回収部４９の内壁下面４９ｂから、第１排出配管５１の導出口５１ａの最遠部までの距離をＬ２とする。このとき、距離Ｌ１は、距離Ｌ２よりも長い。つまり、距離Ｌ１は、距離Ｌ２から、生成物回収部４９の内壁下面４９ｂから内壁上面４９ａ直近までの距離Ｌ３までの範囲に規定することができる。また、第１本体部７０の外径Ｄ１は、第１排出配管５１の内径Ｄ３よりも大きくてもよい。 Here, with respect to the portion of the second catalyst body 42 housed in the first recovery space S3, the tip of the second catalyst body 42 on the opposite side of the flange portion 43 from the inner wall lower surface 49b of the product recovery portion 49. Let L1 be the distance to. On the other hand, the distance from the lower surface 49b of the inner wall of the product recovery unit 49 to the farthest portion of the outlet 51a of the first discharge pipe 51 is L2. At this time, the distance L1 is longer than the distance L2. That is, the distance L1 can be defined in the range from the distance L2 to the distance L3 from the inner wall lower surface 49b of the product recovery unit 49 to the nearest inner wall upper surface 49a. Further, the outer diameter D1 of the first main body 70 may be larger than the inner diameter D3 of the first discharge pipe 51.
　なお、生成物回収部４９において第１排出配管５１が設けられる位置は、上記例示のような生成物回収部４９の側壁部に限られない。 The position where the first discharge pipe 51 is provided in the product recovery unit 49 is not limited to the side wall portion of the product collection unit 49 as in the above example.
　図１５は、図５に対応して描画された、他の生成物回収部４９の形状を示す図である。図１５に示す生成物回収部４９では、上記の第１排出配管５１に代わる第１排出配管８０が、Ｚ方向の一方の壁部に設けられている。なお、図１５では、図５と同様に、接続部５２が生成物回収部４９のＺ方向の下部の壁部、すなわち、生成物回収部４９の内壁下面４９ｂ側に設けられている場合を例示している。この場合、第１排出配管８０は、生成物回収部４９のＺ方向の上部の壁部、すなわち、生成物回収部４９の内壁上面４９ａ側に設けられてもよい。反対に、接続部５２が生成物回収部４９のＺ方向の上部の壁部に設けられている場合には、第１排出配管８０は、生成物回収部４９のＺ方向の下部の壁部に設けられてもよい。 FIG. 15 is a diagram showing the shape of another product recovery unit 49 drawn corresponding to FIG. 5. In the product recovery unit 49 shown in FIG. 15, a first discharge pipe 80 instead of the first discharge pipe 51 is provided on one wall portion in the Z direction. Note that FIG. 15 illustrates a case where the connection portion 52 is provided on the lower wall portion of the product recovery portion 49 in the Z direction, that is, on the lower surface surface 49b side of the inner wall of the product recovery portion 49, as in FIG. is doing. In this case, the first discharge pipe 80 may be provided on the upper wall portion of the product recovery unit 49 in the Z direction, that is, on the inner wall upper surface 49a side of the product recovery unit 49. On the contrary, when the connection portion 52 is provided on the upper wall portion in the Z direction of the product recovery portion 49, the first discharge pipe 80 is provided on the lower wall portion in the Z direction of the product recovery portion 49. It may be provided.
　ここで、第１排出配管８０の内径Ｄ４は、図５に示した第１排出配管５１の内径Ｄ３と同様でもよい。一方、図１５の例示のように、生成物回収部４９において、第１排出配管８０の導出口８０ａと、接続部５２の開口部５２ａとが対向する場合には、第１排出配管８０の内径Ｄ４は、開口部５２ａの開口径Ｄ２と同様でもよい。この場合、第１本体部７０の長さは、図１５に示す距離Ｌ３のように、生成物回収部４９の内壁下面４９ｂから内壁上面４９ａ直近まで延伸する長さとすることが望ましい。このような構成によれば、生成物回収部４９を通過して第１排出配管８０の導出口８０ａに向かう流体は、より第２触媒体４２に接触しやすくなる。 Here, the inner diameter D4 of the first discharge pipe 80 may be the same as the inner diameter D3 of the first discharge pipe 51 shown in FIG. On the other hand, as in the example of FIG. 15, when the outlet 80a of the first discharge pipe 80 and the opening 52a of the connection portion 52 face each other in the product recovery unit 49, the inner diameter of the first discharge pipe 80 D4 may be the same as the opening diameter D2 of the opening 52a. In this case, it is desirable that the length of the first main body portion 70 is a length extending from the inner wall lower surface 49b of the product recovery portion 49 to the immediate vicinity of the inner wall upper surface 49a, as shown by the distance L3 shown in FIG. According to such a configuration, the fluid passing through the product recovery unit 49 and heading toward the outlet 80a of the first discharge pipe 80 is more likely to come into contact with the second catalyst body 42.
　また、第１排出配管８０の内径Ｄ４が開口部５２ａの開口径Ｄ２と同様である場合、外径Ｄ１である第１本体部７０が第１排出配管８０の導出口８０ａに進入できる。そこで、不図示であるが、第１本体部７０の長さを、距離Ｌ３よりもさらに長くすることで、第１本体部７０の先端部が、接続部５２の開口部５２ａの対向位置にある第１排出配管８０の導出口８０ａに進入する程度の長さとしてもよい。このような構成によれば、生成物回収部４９を通過して第１排出配管８０の導出口８０ａに向かう流体の大部分が、第２触媒体４２に接触することになる。 Further, when the inner diameter D4 of the first discharge pipe 80 is the same as the opening diameter D2 of the opening 52a, the first main body 70 having the outer diameter D1 can enter the outlet 80a of the first discharge pipe 80. Therefore, although not shown, the length of the first main body 70 is made longer than the distance L3 so that the tip of the first main body 70 is at a position facing the opening 52a of the connection 52. The length may be such that it enters the outlet 80a of the first discharge pipe 80. According to such a configuration, most of the fluid passing through the product recovery unit 49 and heading for the outlet 80a of the first discharge pipe 80 comes into contact with the second catalyst body 42.
　図１６は、図１５と同様に図５に対応して描画された、他の生成物回収部４９の形状を示す図である。図１６に示す生成物回収部４９では、上記の第１排出配管５１に代えて、２つの排出配管が設けられている。一方の第１排出配管８１は、Ｚ方向の上部の壁部、すなわち、生成物回収部４９の内壁上面４９ａ側に設けられている。他方の第１排出配管８１は、Ｚ方向の下部の壁部、すなわち、生成物回収部４９の内壁下面４９ｂ側に設けられている。 FIG. 16 is a diagram showing the shape of another product recovery unit 49 drawn corresponding to FIG. 5 in the same manner as in FIG. In the product recovery unit 49 shown in FIG. 16, two discharge pipes are provided in place of the first discharge pipe 51 described above. On the other hand, the first discharge pipe 81 is provided on the upper wall portion in the Z direction, that is, on the inner wall upper surface surface 49a side of the product recovery portion 49. The other first discharge pipe 81 is provided on the lower wall portion in the Z direction, that is, on the lower surface surface 49b side of the inner wall of the product recovery portion 49.
　この場合、一方の第１排出配管８１及び他方の第２排出配管８２は、それぞれ、図１５に例示した第１排出配管８０と同様の形状を有する。例えば、第１排出配管８１及び第２排出配管８２の内径は、それぞれ、第１排出配管８０の内径と同様にＤ４であってもよい。 In this case, the first discharge pipe 81 on one side and the second discharge pipe 82 on the other side have the same shape as the first discharge pipe 80 illustrated in FIG. 15, respectively. For example, the inner diameters of the first discharge pipe 81 and the second discharge pipe 82 may be D4, respectively, like the inner diameter of the first discharge pipe 80.
　ただし、第１排出配管８１は、導出口８１ａに第２触媒体４２の第１本体部７０を貫通させた状態で、第２触媒体４２のフランジ部４３を取付可能とする第１フランジ部８１ｂを有する。つまり、第１フランジ部８１ｂは、フランジ部４３の複数の貫通穴４３ａの位置に対応して設けられる複数の貫通穴８１ｃを有する。 However, in the first discharge pipe 81, the first flange portion 81b to which the flange portion 43 of the second catalyst body 42 can be attached while the first main body portion 70 of the second catalyst body 42 is passed through the outlet port 81a. Have. That is, the first flange portion 81b has a plurality of through holes 81c provided corresponding to the positions of the plurality of through holes 43a of the flange portion 43.
　また、第１排出配管８１には、第２触媒体４２のフランジ部４３を介して、外部配管８３が連結される。外部配管８３は、第１フランジ部８１ｂと同様に、第２触媒体４２のフランジ部４３を取付可能とする第２フランジ部８３ｂを有する。なお、外部配管８３の開口部８３ａは、第１排出配管８１の導出口８１ａと同様の寸法を有する。また、第１フランジ部８１ｂ及び第２フランジ部８３ｂは、それぞれ、第２触媒体４２のフランジ部４３に形成されているガスケット溝５２ｃと同様に、ガスケット６６を取り付けるためのガスケット溝を有する。つまり、フランジ部４３が第１フランジ部８１ｂと第２フランジ部８３ｂとに挟み込まれて、貫通穴８１ｃ及び貫通穴８３ｃを貫通したボルト６５で締結されることで、第１排出配管８１には、外部配管８３が取り付けられるとともに、第２触媒体４２が保持される。 Further, the external pipe 83 is connected to the first discharge pipe 81 via the flange portion 43 of the second catalyst body 42. The external pipe 83 has a second flange portion 83b to which the flange portion 43 of the second catalyst body 42 can be attached, similarly to the first flange portion 81b. The opening 83a of the external pipe 83 has the same dimensions as the outlet 81a of the first discharge pipe 81. Further, the first flange portion 81b and the second flange portion 83b each have a gasket groove for attaching the gasket 66, similarly to the gasket groove 52c formed in the flange portion 43 of the second catalyst body 42. That is, the flange portion 43 is sandwiched between the first flange portion 81b and the second flange portion 83b, and is fastened to the first discharge pipe 81 by a bolt 65 penetrating the through hole 81c and the through hole 83c. The external pipe 83 is attached, and the second catalyst body 42 is held.
　一方、第２触媒体４２が第１排出配管８１に保持される場合、生成物回収部４９から外部配管８３に向けて流体が流通可能となるように、第２触媒体４２の支持部４４は、第１本体部７０側から外部配管８３の開口部８３ａ側に連通する貫通穴４４ａを有する。また、第２触媒体４２が第１排出配管８１に保持される場合であっても、第２触媒体４２の長さは、図１５を用いて説明したように設定され得る。 On the other hand, when the second catalyst body 42 is held in the first discharge pipe 81, the support portion 44 of the second catalyst body 42 has a support portion 44 so that the fluid can flow from the product recovery portion 49 to the external pipe 83. It has a through hole 44a that communicates from the first main body 70 side to the opening 83a side of the external pipe 83. Further, even when the second catalyst body 42 is held in the first discharge pipe 81, the length of the second catalyst body 42 can be set as described with reference to FIG.
　そして、このような構成によれば、生成物回収部４９が第１排出配管８１と第２排出配管８２とを有する場合でも、第２触媒体４２と接触した流体を双方の排出配管に向かわせることができる。 According to such a configuration, even when the product recovery unit 49 has the first discharge pipe 81 and the second discharge pipe 82, the fluid in contact with the second catalyst 42 is directed to both discharge pipes. be able to.
　また、生成物回収部４９は、第２排出配管８２を設けずに、第１排出配管８１のみを設ける構成としてもよい。つまり、生成物回収部４９は、図５に例示したような第１排出配管５１及び接続部５２を設けていなくても、第１フランジ部８１ｂを有する第１排出配管８１を設けてさえいれば、外部配管８３との連結に合わせて、容易に第２触媒体４２を保持することができる。 Further, the product recovery unit 49 may be configured to provide only the first discharge pipe 81 without providing the second discharge pipe 82. That is, even if the product recovery unit 49 is not provided with the first discharge pipe 51 and the connection portion 52 as illustrated in FIG. 5, as long as the first discharge pipe 81 having the first flange portion 81b is provided. The second catalyst body 42 can be easily held in accordance with the connection with the external pipe 83.

Further, the heat medium introduction unit 53 has a second introduction pipe 55 that introduces the heat medium HC from the outside to the inside. The second introduction pipe 55 faces approximately the center of the second side surface 61 on the XZ plane, and is connected along the opening direction of the plurality of second introduction ports 30. According to the heat medium introduction unit 53, the heat medium HC introduced from one second introduction pipe 55 is distributed to each of the plurality of second introduction ports 30.
　熱媒体回収部５７は、熱媒体流路３１を流通した熱媒体ＨＣを回収する第２回収空間Ｓ４を有する第２導管部である。本実施形態では、熱媒体回収部５７は、１つの面を開放面とする箱形状を有し、第２伝熱体９の第２排出口３５が開放面に含まれるように、熱交換部３の第３側面６２に設置される。つまり、第２排出口３５を含む第２伝熱体９の側面の一部は、熱媒体回収部５７の内壁の一部となる。また、熱媒体回収部５７は、熱媒体ＨＣを反応装置１の外部へ排出する第２排出配管５９を有する。 The heat medium recovery unit 57 is a second conduit unit having a second recovery space S4 for recovering the heat medium HC flowing through the heat medium flow path 31. In the present embodiment, the heat medium recovery unit 57 has a box shape with one surface as an open surface, and the heat exchange unit is included so that the second discharge port 35 of the second heat transfer body 9 is included in the open surface. It is installed on the third side surface 62 of 3. That is, a part of the side surface of the second heat transfer body 9 including the second discharge port 35 becomes a part of the inner wall of the heat medium recovery unit 57. Further, the heat medium recovery unit 57 has a second discharge pipe 59 that discharges the heat medium HC to the outside of the reaction device 1.

On the other hand, as the heat medium HC, a substance that does not corrode the constituent material of the heat exchange unit 3 is suitable, and in the case of a high temperature gas as in the present embodiment, a gaseous substance such as combustion gas or heated air is used. can. In addition, for example, it may be a liquid substance such as water and oil. However, when a gaseous substance is used as the heat medium HC, it is easier to handle than when a liquid medium is used.
　次に、本実施形態に係る反応装置１の作用について説明する。 Next, the operation of the reaction device 1 according to the present embodiment will be described.
　まず、反応流体Ｍに関して、第１導入配管４７から反応流体導入部４５に導入された反応流体Ｍは、第１導入空間Ｓ１において複数の第１導入口２０のそれぞれに分配される。反応流体Ｍは、各々の第１導入口２０から反応流路１７に導入されて、第１流路２２内をＹ方向に沿って流通する。 First, regarding the reaction fluid M, the reaction fluid M introduced from the first introduction pipe 47 into the reaction fluid introduction unit 45 is distributed to each of the plurality of first introduction ports 20 in the first introduction space S1. The reaction fluid M is introduced into the reaction flow path 17 from each first introduction port 20 and flows in the first flow path 22 along the Y direction.
　一方、熱媒体ＨＣに関して、第２導入配管５５から熱媒体導入部５３に導入された熱媒体ＨＣは、第２導入空間Ｓ２において複数の第２導入口３０のそれぞれに分配される。熱媒体ＨＣは、各々の第２導入口３０から熱媒体流路３１に導入されて、第２流路３６内を流通する。本実施形態では、第２流路３６も第１流路２２に合わせてＹ方向に沿って形成されているが、熱媒体ＨＣの流通方向は、反応流体Ｍの流通方向とは反対である。 On the other hand, regarding the heat medium HC, the heat medium HC introduced from the second introduction pipe 55 to the heat medium introduction unit 53 is distributed to each of the plurality of second introduction ports 30 in the second introduction space S2. The heat medium HC is introduced into the heat medium flow path 31 from each second introduction port 30 and circulates in the second flow path 36. In the present embodiment, the second flow path 36 is also formed along the Y direction in accordance with the first flow path 22, but the flow direction of the heat medium HC is opposite to the flow direction of the reaction fluid M.
　反応流体Ｍと熱媒体ＨＣとの流通により、熱交換部３では、反応流体Ｍと熱媒体ＨＣとの間で熱交換が行われ、反応流体Ｍが加熱される。そして、第１流路２２では、第１触媒体４１の反応促進作用も相まって、反応流体Ｍが反応温度で吸熱反応し、生成物Ｐが生成される。生成物Ｐは、第１合流流路２３を通じて、第１排出口２１から生成物回収部４９内の第１回収空間Ｓ３に排出される。 Due to the flow between the reaction fluid M and the heat medium HC, heat exchange is performed between the reaction fluid M and the heat medium HC in the heat exchange unit 3, and the reaction fluid M is heated. Then, in the first flow path 22, the reaction fluid M undergoes an endothermic reaction at the reaction temperature in combination with the reaction promoting action of the first catalyst body 41, and the product P is produced. The product P is discharged from the first discharge port 21 to the first recovery space S3 in the product recovery unit 49 through the first confluence flow path 23.
　ここで、第１排出口２１から排出される流体には、反応流路１７内で生成された生成物Ｐのほかに、生成物Ｐの生成に寄与しなかった反応原料が残存している場合もある。そのため、なんら対策を採らなければ、このような残存した反応原料と生成物Ｐとを含む流体は、そのまま反応装置１の外部へ排出されることになる。 Here, in the case where the fluid discharged from the first discharge port 21 contains the reaction raw material that did not contribute to the production of the product P, in addition to the product P generated in the reaction flow path 17. There is also. Therefore, if no measures are taken, the fluid containing the remaining reaction raw material and the product P will be discharged to the outside of the reaction apparatus 1 as it is.
　これに対して、本実施形態では、生成物回収部４９の第１回収空間Ｓ３内に第２触媒体４２が備えられている。また、第１回収空間Ｓ３内に排出される流体は、第１排出口２１から排出された直後であるので、高温を維持している。そのため、反応流路１７内で生成物Ｐの生成に寄与しなかった反応原料は、自己熱により、第１回収空間Ｓ３内で改めて反応促進される。したがって、生成物回収部４９から第１排出配管５１を通じて反応装置１の外部に排出される流体中では、生成物Ｐの生成に寄与しなかった反応原料の残存率は、第２触媒体４２を用いない場合に比べて低くなる。 On the other hand, in the present embodiment, the second catalyst body 42 is provided in the first recovery space S3 of the product recovery unit 49. Further, since the fluid discharged into the first recovery space S3 is immediately after being discharged from the first discharge port 21, the high temperature is maintained. Therefore, the reaction raw material that did not contribute to the formation of the product P in the reaction flow path 17 is promoted again in the first recovery space S3 by the self-heat. Therefore, in the fluid discharged from the product recovery unit 49 to the outside of the reaction device 1 through the first discharge pipe 51, the residual ratio of the reaction raw material that did not contribute to the production of the product P is the second catalyst 42. It will be lower than when not used.
　なお、第２流路３６を流通して熱交換に利用された熱媒体ＨＣは、第２合流流路３７を通じて、第２排出口３５から熱媒体回収部５７内の第２回収空間Ｓ４に排出される。第２回収空間Ｓ４で回収された熱媒体ＨＣは、第２排出配管５９を通じて反応装置１の外部に排出される。 The heat medium HC flowing through the second flow path 36 and used for heat exchange is discharged from the second discharge port 35 to the second recovery space S4 in the heat medium recovery section 57 through the second confluence flow path 37. Will be done. The heat medium HC recovered in the second recovery space S4 is discharged to the outside of the reaction device 1 through the second discharge pipe 59.
　次に、本実施形態に係る反応装置１による効果について説明する。 Next, the effect of the reaction device 1 according to the present embodiment will be described.
　反応装置１は、反応原料を含む第１流体を流通させる第１流路２２を有する第１伝熱体７と、第１伝熱体７に積層され、第１流体との熱交換に用いられる第２流体を流通させる第２流路３６を有する第２伝熱体９とを備える。反応装置１は、第１伝熱体７にある第１流路２２に連通する第１排出口２１に面する第１回収空間Ｓ３を有し、反応原料の吸熱反応により第１流路２２で生成された生成物Ｐを回収する生成物回収部４９を備える。また、反応装置１は、生成物回収部４９に設置され、第１流路２２にて残存して第１回収空間Ｓ３に排出された反応原料の吸熱反応を促進させる触媒を備える。 The reactor 1 is laminated on the first heat transfer body 7 and the first heat transfer body 7 having the first flow path 22 through which the first fluid containing the reaction raw material flows, and is used for heat exchange with the first fluid. A second heat transfer body 9 having a second flow path 36 through which a second fluid flows is provided. The reactor 1 has a first recovery space S3 facing the first discharge port 21 communicating with the first flow path 22 in the first heat transfer body 7, and is in the first flow path 22 due to the endothermic reaction of the reaction raw material. A product recovery unit 49 for recovering the generated product P is provided. Further, the reaction apparatus 1 is installed in the product recovery unit 49 and includes a catalyst that promotes the endothermic reaction of the reaction raw material remaining in the first flow path 22 and discharged into the first recovery space S3.
　ここで、第１流体とは、本実施形態では反応流体Ｍに相当する。第２流体とは、本実施形態では熱媒体ＨＣに相当する。なお、別の実施形態として、例えば、第１流体及び第２流体がともに反応流体であってもよい。 Here, the first fluid corresponds to the reaction fluid M in this embodiment. The second fluid corresponds to the heat medium HC in this embodiment. As another embodiment, for example, both the first fluid and the second fluid may be reaction fluids.
　本実施形態では、生成物回収部４９の第１回収空間Ｓ３内に、第２触媒体４２等の触媒が備えられているので、反応流路１７内で生成物Ｐの生成に寄与しなかった反応原料に対して、第１回収空間Ｓ３内で改めて反応促進が行われる。つまり、反応装置１全体として捉えた場合に、第２触媒体４２のような触媒を用いない場合に比べて、より多くの生成物Ｐが得られることになる。特に、本実施形態によれば、平衡組成に近づけるために、熱交換部３での熱交換に用いる熱媒体ＨＣの温度や流量などを増加させる必要がなくなる。一方で、第２触媒体４２等の触媒を用いない場合のときの生成物Ｐの生成量が所望の量である場合には、本実施形態のように第２触媒体４２等の触媒を用いることで、熱媒体ＨＣの温度や流量を低減させることができる。また、反応装置１から排出される生成物Ｐの温度は、第２触媒体４２のような触媒を用いない場合に比べて低下する。例えば、反応装置１の下流側におけるプロセス上又は機器設計上の何らかの制約により、生成物Ｐの温度を反応装置１から排出された時点より低下させるための除熱・冷却機構の設置が要求される場合がある。このような場合において、本実施形態によれば、その機構の負荷が低減され、又は、設計条件が緩和される。 In the present embodiment, since the catalyst such as the second catalyst body 42 is provided in the first recovery space S3 of the product recovery unit 49, it does not contribute to the formation of the product P in the reaction flow path 17. The reaction of the reaction raw material is promoted again in the first recovery space S3. That is, when the reaction apparatus 1 is taken as a whole, a larger amount of product P can be obtained as compared with the case where a catalyst such as the second catalyst 42 is not used. In particular, according to the present embodiment, it is not necessary to increase the temperature and flow rate of the heat medium HC used for heat exchange in the heat exchange unit 3 in order to approach the equilibrium composition. On the other hand, when the amount of product P produced when the catalyst such as the second catalyst 42 is not used is a desired amount, the catalyst such as the second catalyst 42 is used as in the present embodiment. As a result, the temperature and flow rate of the heat medium HC can be reduced. Further, the temperature of the product P discharged from the reactor 1 is lower than that in the case where a catalyst such as the second catalyst 42 is not used. For example, due to some restrictions on the process or equipment design on the downstream side of the reaction device 1, it is required to install a heat removal / cooling mechanism for lowering the temperature of the product P from the time when the product P is discharged from the reaction device 1. In some cases. In such a case, according to the present embodiment, the load of the mechanism is reduced or the design conditions are relaxed.
　このように、本実施形態によれば、反応のために与えられた熱量をより有効に活用するのに有利となる反応装置１を提供することができる。 As described above, according to the present embodiment, it is possible to provide the reactor 1 which is advantageous for more effectively utilizing the amount of heat given for the reaction.
　また、反応装置１は、触媒を含む本体部を有する第２触媒体４２を備えてもよい。この場合、生成物回収部４９は、本体部を第１回収空間Ｓ３に収容させる開口部５２ａを含む接続部５２を有してもよい。また、第２触媒体４２は、本体部を第１回収空間Ｓ３に収容させた状態で、接続部５２に取り付けられるフランジ部４３を有してもよい。 Further, the reaction device 1 may include a second catalyst body 42 having a main body portion including a catalyst. In this case, the product recovery unit 49 may have a connection unit 52 including an opening 52a for accommodating the main body unit in the first collection space S3. Further, the second catalyst body 42 may have a flange portion 43 attached to the connection portion 52 in a state where the main body portion is housed in the first recovery space S3.
　このような反応装置１によれば、作業者による第２触媒体４２の取り付け又は取り外し等の作業が容易となる。 According to such a reaction device 1, the work such as attachment or removal of the second catalyst body 42 by the operator becomes easy.
　また、反応装置１は、触媒を含む本体部を有する第２触媒体４２を備えてもよい。この場合、生成物回収部４９は、生成物Ｐを外部配管８３へ排出する第１排出配管８１を有してもよい。また、第２触媒体４２は、本体部を第１回収空間Ｓ３に収容させた状態で、第１排出配管８１に取り付けられるフランジ部４３を有してもよい。 Further, the reaction device 1 may include a second catalyst body 42 having a main body portion including a catalyst. In this case, the product recovery unit 49 may have a first discharge pipe 81 that discharges the product P to the external pipe 83. Further, the second catalyst body 42 may have a flange portion 43 attached to the first discharge pipe 81 in a state where the main body portion is housed in the first recovery space S3.
　このような反応装置１によれば、作業者による第２触媒体４２の取り付け又は取り外し等の作業が容易となる。また、生成物回収部４９は、上記のような接続部５２を設けていなくても、第１排出配管８１を介して第２触媒体４２を保持することができる。 According to such a reaction device 1, the work such as attachment or removal of the second catalyst body 42 by the operator becomes easy. Further, the product recovery unit 49 can hold the second catalyst body 42 via the first discharge pipe 81 even if the connection unit 52 as described above is not provided.
　また、反応装置１では、第１排出配管８１は、外部配管８３との連結に用いられる第１フランジ部８１ｂを有してもよい。外部配管８３は、第１フランジ部８１ｂと接続可能な第２フランジ部８３ｂを有してもよい。この場合、フランジ部４３は、第１フランジ部８１ｂと第２フランジ部８３ｂとに挟まれて締結されてもよい。 Further, in the reaction device 1, the first discharge pipe 81 may have a first flange portion 81b used for connection with the external pipe 83. The external pipe 83 may have a second flange portion 83b that can be connected to the first flange portion 81b. In this case, the flange portion 43 may be sandwiched between the first flange portion 81b and the second flange portion 83b and fastened.
　このような反応装置１によれば、作業者による第２触媒体４２の取り付け又は取り外し等の作業が、第１排出配管８１と外部配管８３との連結作業に合わせて行うことができることになり、結果として、作業工程を単純化させることができる。 According to such a reaction device 1, the work of attaching or removing the second catalyst body 42 by the operator can be performed in accordance with the work of connecting the first discharge pipe 81 and the external pipe 83. As a result, the work process can be simplified.
　また、反応装置１では、本体部は、筒状又は柱状であってもよい。 Further, in the reaction device 1, the main body may be cylindrical or columnar.
　このような反応装置１によれば、本体部を、接続部５２や第１排出配管８１から生成物回収部４９の第１回収空間Ｓ３に進入しやすくすることができる。また、本体部における第１回収空間Ｓ３に面する部分の表面積をより多く取ることができるため、第１回収空間Ｓ３内での触媒による反応をより促進させることができる。 According to such a reaction device 1, the main body can be easily entered into the first recovery space S3 of the product recovery section 49 from the connection section 52 and the first discharge pipe 81. Further, since the surface area of the portion of the main body portion facing the first recovery space S3 can be increased, the reaction by the catalyst in the first recovery space S3 can be further promoted.
　また、反応装置１では、本体部は、触媒を担持する構造材を有してもよい。 Further, in the reaction device 1, the main body may have a structural material for supporting the catalyst.
　このような反応装置１によれば、触媒が構造材に担持されているので、本体部全体、引いては第２触媒体４２全体が強固となる。したがって、例えば、第２触媒体４２は、触媒を長期間に渡って第１回収空間Ｓ３に保持しやすくなる。また、例えば、作業者による第２触媒体４２の取り付け又は取り外し等の作業時に、第２触媒体４２の破損等が生じづらくなる。 According to such a reaction device 1, since the catalyst is supported on the structural material, the entire main body portion, and thus the entire second catalyst body 42, becomes strong. Therefore, for example, the second catalyst 42 can easily hold the catalyst in the first recovery space S3 for a long period of time. Further, for example, when the operator attaches or removes the second catalyst body 42, the second catalyst body 42 is less likely to be damaged.
　また、反応装置１では、触媒は、多孔質状であってもよい。ここで、多孔質状の触媒を含む本体部は、例えば第５本体部７４である。 Further, in the reaction device 1, the catalyst may be porous. Here, the main body portion containing the porous catalyst is, for example, the fifth main body portion 74.
　このような反応装置１によれば、本体部は、例えば、触媒を担持する構造材を用いなくても、触媒単体で構成されることもあり得る。また、触媒が多孔質状であると、第１回収空間Ｓ３にある流体との接触面積が増えるため、第１回収空間Ｓ３内での触媒による反応をより促進させることができる。 According to such a reaction device 1, the main body may be composed of a single catalyst, for example, without using a structural material for supporting the catalyst. Further, when the catalyst is porous, the contact area with the fluid in the first recovery space S3 increases, so that the reaction by the catalyst in the first recovery space S3 can be further promoted.
　また、反応装置１では、触媒は、ペレット状であってもよい。この場合、本体部は、ペレット状の触媒を収容する筒体を有してもよい。ここで、本体部は、例えば第７本体部７６である。 Further, in the reaction device 1, the catalyst may be in the form of pellets. In this case, the main body may have a cylinder containing a pellet-shaped catalyst. Here, the main body portion is, for example, the seventh main body portion 76.
　このような反応装置１によれば、例えば、使用済みの触媒と新たな触媒とを交換する場合に、筒体に収容されているペレット状の触媒７６ａを入れ替えるだけで済む。したがって、触媒を構造材に担持させた本体部を多数準備する必要がなくなる。また、ペレット状の触媒７６ａが筒体に収容されている状態では、触媒同士の隙間が多数存在することになり、第１回収空間Ｓ３にある流体との接触面積が増えるため、第１回収空間Ｓ３内での触媒による反応をより促進させることができる。 According to such a reaction device 1, for example, when exchanging a used catalyst with a new catalyst, it is only necessary to replace the pellet-shaped catalyst 76a housed in the cylinder. Therefore, it is not necessary to prepare a large number of main bodies in which the catalyst is supported on the structural material. Further, in the state where the pellet-shaped catalyst 76a is housed in the cylinder, there are many gaps between the catalysts, and the contact area with the fluid in the first recovery space S3 increases, so that the first recovery space The catalytic reaction in S3 can be further promoted.
　また、反応装置１では、構造材は、本体部が筒状である場合には筒状であり、かつ、筒外部と筒内部とで貫通する複数の貫通穴を有してもよい。 Further, in the reaction device 1, the structural material may be cylindrical when the main body portion is tubular, and may have a plurality of through holes penetrating between the outside of the cylinder and the inside of the cylinder.
　このような反応装置１によれば、第１回収空間Ｓ３にある流体が、複数の貫通穴を介して筒状の構造材の筒外部と筒内部とで行き来することができるため、より触媒に接触しやすくなる。 According to such a reaction device 1, the fluid in the first recovery space S3 can move back and forth between the outside of the cylinder and the inside of the cylinder of the tubular structural material through a plurality of through holes, so that the catalyst can be used more. It becomes easier to contact.
　また、反応装置１では、構造材は、断面がハニカム状となるハニカム構造体を含んでもよい。ここで、本体部は、例えば第２本体部７１である。 Further, in the reaction device 1, the structural material may include a honeycomb structure having a honeycomb-like cross section. Here, the main body portion is, for example, the second main body portion 71.
　ハニカム構造体７１ａは、空間領域を広く確保しながら、全体として広い表面積を有する。したがって、このような反応装置１によれば、例えば、触媒を構造材の表面全体に担持させることで、第１回収空間Ｓ３内の流体との接触面積を、第１本体部７０の場合よりも広くすることができる。 The honeycomb structure 71a has a large surface area as a whole while securing a wide space area. Therefore, according to such a reaction device 1, for example, by supporting the catalyst on the entire surface of the structural material, the contact area with the fluid in the first recovery space S3 is larger than that in the case of the first main body 70. Can be wide.
　また、反応装置１では、構造材は、断面が波状に湾曲したコルゲート板を筒型に丸められたコルゲート構造体を含んでもよい。ここで、本体部は、例えば第３本体部７２である。 Further, in the reaction device 1, the structural material may include a corrugated structure in which a corrugated plate having a wavy cross section is rolled into a tubular shape. Here, the main body portion is, for example, the third main body portion 72.
　コルゲート構造体７３ａは、空間領域を広く確保しながら、全体として広い表面積を有する。したがって、このような反応装置１によれば、例えば、触媒を構造材の表面全体に担持させることで、第１回収空間Ｓ３内の流体との接触面積を、第１本体部７０の場合よりも広くすることができる。 The corrugated structure 73a has a large surface area as a whole while securing a wide space area. Therefore, according to such a reaction device 1, for example, by supporting the catalyst on the entire surface of the structural material, the contact area with the fluid in the first recovery space S3 is larger than that in the case of the first main body 70. Can be wide.
　なお、反応流路１７に設置される第１触媒体４１は、上記のとおり、断面が波状に丸く湾曲したコルゲート板状の棒体であってもよい。そこで、このようなコルゲート板状の棒体である第１触媒体４１を採用する場合には、第１触媒体４１の構造材を構成するコルゲート板を流用し、当該コルゲート板を筒型に丸めることで、第３本体部７２に用いる構造材としてもよい。つまり、第１触媒体４１と第２触媒体４２との双方を反応装置１に採用する場合には、第１触媒体４１又は第２触媒体４２のそれぞれの構造材となる基材を個別に準備する必要がないという利点もある。 As described above, the first catalyst body 41 installed in the reaction flow path 17 may be a corrugated plate-shaped rod whose cross section is curved in a wavy shape. Therefore, when the first catalyst body 41, which is such a corrugated plate-shaped rod, is adopted, the corrugated plate constituting the structural material of the first catalyst body 41 is diverted and the corrugated plate is rolled into a tubular shape. Therefore, it may be used as a structural material for the third main body portion 72. That is, when both the first catalyst body 41 and the second catalyst body 42 are adopted in the reaction device 1, the base materials used as the structural materials of the first catalyst body 41 or the second catalyst body 42 are individually used. It also has the advantage of not having to be prepared.

In this case, the main body may include a plurality of tubular or rod-shaped structural materials. Here, the main body portion is, for example, the sixth main body portion 75.
　このような反応装置１によれば、例えば、予め触媒を担持した筒状又は棒状の構造材が複数存在する場合には、それらの構造材を集合させて１つの束とすることで、容易に本体部を構成させることができる。 According to such a reaction device 1, for example, when there are a plurality of tubular or rod-shaped structural materials on which a catalyst is supported in advance, those structural materials can be easily aggregated into one bundle. The main body can be configured.
　また、反応装置１では、構造材は、複数の盤体を含んでもよい。この場合、本体部は、複数の盤体を、本体部の筒状又は柱状の延伸方向に並べて保持する保持体を含んでもよい。ここで、本体部は、例えば第８本体部７７である。 Further, in the reaction device 1, the structural material may include a plurality of boards. In this case, the main body may include a holding body that holds a plurality of boards side by side in the tubular or columnar stretching direction of the main body. Here, the main body portion is, for example, the eighth main body portion 77.
　このような反応装置１によれば、例えば、予め触媒を担持した盤体７７ａ等の構造材が複数存在する場合には、それらの構造材を保持体７７ｂに保持させることで、容易に本体部を構成させることができる。 According to such a reaction device 1, for example, when a plurality of structural materials such as a board 77a on which a catalyst is supported in advance are present, the structural materials are held by the holding body 77b so that the main body portion can be easily used. Can be configured.
　また、反応装置１では、構造材は、本体部の筒状又は柱状の延伸方向に合わせてスパイラル状に延伸する板構造体であってもよい。ここで、本体部は、例えば第９本体部７８である。 Further, in the reaction device 1, the structural material may be a plate structure that is spirally stretched in a cylindrical or columnar stretching direction of the main body. Here, the main body portion is, for example, the ninth main body portion 78.
　このような反応装置１によれば、例えば、予め触媒を担持した板構造体７８ａを、保持体７８ｂから突出する複数の支持棒７８ｃを介して保持体７８ｂに保持させることで、容易に本体部を構成させることができる。特に、板構造体７８ａの形状がスパイラル状である場合には、板構造体７８ａは、第１回収空間Ｓ３内の流体の流通方向を、スパイラル形状に合わせて延伸方向に規定することができる。したがって、このような反応装置１によれば、板構造体７８ａは、触媒による反応を促進させつつ、流体を所望の方向である例えば第１排出配管８０に向けて流通させやすくすることができる。 According to such a reaction device 1, for example, the plate structure 78a on which the catalyst is previously supported is held by the holding body 78b via a plurality of support rods 78c protruding from the holding body 78b, so that the main body portion can be easily obtained. Can be configured. In particular, when the shape of the plate structure 78a is spiral, the plate structure 78a can define the flow direction of the fluid in the first recovery space S3 in the stretching direction according to the spiral shape. Therefore, according to such a reaction device 1, the plate structure 78a can facilitate the flow of the fluid in a desired direction, for example, toward the first discharge pipe 80, while promoting the reaction by the catalyst.
　また、反応装置１では、本体部は、第１排出口２１に対向してもよい。 Further, in the reaction device 1, the main body may face the first discharge port 21.
　このような反応装置１によれば、第１排出口２１から排出された生成物Ｐを含む流体が本体部に突き当たるので、第１回収空間Ｓ３内での触媒による反応をより促進させることができる。 According to such a reaction device 1, since the fluid containing the product P discharged from the first discharge port 21 abuts on the main body portion, the reaction by the catalyst in the first recovery space S3 can be further promoted. ..

In this case, the catalyst 46 may be supported on the inner wall of the product recovery unit 49, for example, the entire surface of the inner wall side surface 49c. Further, although not shown, the product may be supported on the inner wall upper surface 49a or the inner wall lower surface 49b of the product recovery unit 49.

Next, the reaction apparatus according to the third embodiment will be described. In the present embodiment, instead of the second catalyst body 42 in the first embodiment, a large number of granular catalysts 48 are housed in the entire first recovery space S3.
　図１８は、第３実施形態に係る反応装置１の構成を示す側面図である。図１８では、第１回収空間Ｓ３内にある触媒４８が、一部、点の集合で描画されている。 FIG. 18 is a side view showing the configuration of the reaction device 1 according to the third embodiment. In FIG. 18, the catalyst 48 in the first recovery space S3 is partially drawn as a set of points.
　触媒４８に採用し得る触媒成分は、第１触媒体４１に採用されるものと同様である。この場合、生成物回収部４９は、第１実施形態に係る反応装置１で採用した接続部５２を有してもよい。また、生成物回収部４９は、生成物回収部４９のＺ方向の上部の壁部、すなわち、生成物回収部４９の内壁上面４９ａ側に、開口部５８ａを含む接続部５８を有してもよい。これに合わせて、生成物回収部４９は、接続部５２に対してボルト６５を用いて取り付け可能とする第１ブランクフランジ５４と、接続部５８に対してボルト６５を用いて取り付け可能とする第２ブランクフランジ５６とを備えてもよい。 The catalyst components that can be used in the catalyst 48 are the same as those used in the first catalyst body 41.
