본 발명은 고체 촉매와 액상 반응물의 접촉을 용이하게 하여 반응기의 성능을 향상시키기 위해 반응기의 방해판(baffle) 내부에 촉매를 충진할 수 있는 회분식 반응기에 관한 것이다.The present invention relates to a batch reactor capable of filling a catalyst inside a baffle of the reactor to facilitate contact of the solid catalyst with the liquid phase reactant to improve the performance of the reactor.
일반적으로 회분식 반응기에서는 액상 반응물질과 함께 고체 촉매를 주입하여 교반하는 것이 보통이나, 이 경우 반응이 끝난 후에 액상 반응물질과 고체 촉매를 분리해 내어야 하는 단점이 있고 특히 액상 반응물질과 고체 촉매 사이의 반응에 의해 생성되는 생성물이 고형물일 경우에는 고체 촉매와 고형 생성물간의 분리도 문제점으로 지적된다.In general, in a batch reactor, it is common to inject and stir a solid catalyst together with a liquid reactant, but in this case, there is a disadvantage in that the liquid reactant and the solid catalyst must be separated after the reaction is completed. If the product produced by the reaction is a solid, the separation between the solid catalyst and the solid product is also pointed out as a problem.
또한 액체산을 대체하여 고체산을 사용하여 반응을 수행할 경우 고체산이 액체산에 비견할 수 있는 농도의 산성점을 지니기 위해서는 과량의 고체산의 사용이 불가피하다. 이 경우 반응기의 많은 부분이 고체산으로 채워지게 되어 결국 교반이 불량해지고 반응성이 떨어지게 되는 문제점을 보이게 된다.In addition, when the reaction is performed using a solid acid instead of a liquid acid, the use of an excess of solid acid is inevitable in order to have an acid point of a concentration comparable to that of the liquid acid. In this case, a large part of the reactor is filled with a solid acid, resulting in poor agitation and poor reactivity.
이에 본 발명은 액상 반응물의 교반 효과를 높이기 위해 회분식 반응기에 설치하는 방해판(baffle)을 개조하여 그 내부에 촉매를 충진할 수 있도록 하고, 이에 따라 교반 효과의 향상뿐 아니라, 액상 반응물과 고체 촉매간의 접촉 효과를 월등히 향상시켜 반응성을 크게 높이는데 그 목적이 있다.Accordingly, the present invention is to modify the baffle installed in the batch reactor in order to increase the stirring effect of the liquid reactant to fill the catalyst therein, thereby improving the stirring effect, as well as the liquid reactant and the solid catalyst The purpose is to greatly improve the reactivity by greatly improving the contact effect of the liver.
이하, 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail.
본 발명은 고체 촉매를 이용하여 액상 화학 반응을 실시하는 원통형 회분식 반응기(1)에 있어서, 원통형의 내접면을 따라 고체 촉매가 내부에 충전되는 방해판(2)과, 액상 반응물을 교반시키는 상기 반응기의 중심축(3) 방향으로 교반기(4)가 설치되는 것을 특징으로 하는 촉매 충진 회분식 반응기이다.The present invention is a cylindrical batch reactor (1) for performing a liquid phase chemical reaction using a solid catalyst, the baffle plate (2) in which the solid catalyst is filled along the cylindrical inner surface, and the reactor for stirring the liquid reactant It is a catalyst packed batch reactor characterized in that the stirrer (4) is installed in the direction of the central axis (3).
이하, 본 발명을 첨부 도면을 참조로 더욱 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.
제1도는 본 발명에 의한 촉매 충진 회분식 반응기의 개략 단면도이고, 제2도는 본 발명에 의한 촉매 충진 회분식 반응기의 평단면도이다.1 is a schematic cross-sectional view of a catalyst packed batch reactor according to the present invention, and FIG. 2 is a cross-sectional plan view of a catalyst packed batch reactor according to the present invention.
제1도에 나타난 바와 같이, 원통형의 반응기(1)의 내접면에는 세로 방향으로 방해판(2)이 설치되고, 또한 반응기(1)의 중심축(3)을 따라 교반기(4)가 설치된다. 상기의 방해판(2)은 제2도에 나타난 바와 같이 원주내면을 따라 중심축에서 일정한 간격(40°)을 두고 설치된다. 상기 방해판(2)의 상세한 도면을 제3도에 나타냈다. 제3도에 나타난 바와 같이 상기 방해판(2)은 그물망(5)으로 구성되고, 그의 내부에는 구형태의 고체촉매(6)가 충전된다. 상기 방해판(2)의 두께(t)는 고체 촉매(6)의 평균 입경의 10배 길이로 하고, 상기 방해판(2)의 폭은 방해판 두께(t)의 약 20배로 하고, 방해판(2)의 높이(h)는 원통형의 길이를 따라 상기 폭(w)의 약 8배의 길이로 한다. 또한 상기 방해판(2)의 그물망(5)은 고체 촉매(6) 평균 입경의 약 1/4눈금의 그물망으로 된다. 상기와 같이 본 발명에 의한 반응기는 방해판이 그물망으로 형성되고, 그물망 내부에 고체 촉매가 충전되어 반응기내에서 반응하게 되는 액상 반응물과 고체 촉매의 접촉이 활성화되고, 고체 촉매가 그물망에 의해 고립되어 있기 때문에 반응을 완결한 후에 반응물과 고체 촉매를 별도로 분리하는 공정이 필요치 않다. 또한 상기 방해판이 원통형의 반응기 내부에 제2도에 나타난 바와 같이 다수의 방해판으로, 바람직하게는 9개가 설치되어 있기 때문에 촉매와 반응물의 접촉 활성 효과를 최대화 할 수 있다.As shown in FIG. 1, a baffle plate 2 is installed in the longitudinal direction of the cylindrical reactor 1, and an agitator 4 is provided along the central axis 3 of the reactor 1. . The baffle plate 2 is installed at regular intervals (40 °) from the central axis along the circumferential surface as shown in FIG. The detailed drawing of the said obstruction plate 2 is shown in FIG. As shown in FIG. 3, the baffle plate 2 is composed of a net 5, and a solid catalyst 6 in a spherical shape is filled therein. The thickness t of the baffle plate 2 is 10 times the average particle diameter of the solid catalyst 6, and the width of the baffle plate 2 is about 20 times the b thickness t. The height h of 2 is about eight times the width w along the length of the cylinder. The mesh 5 of the baffle plate 2 is also a mesh of about 1/4 division of the average particle diameter of the solid catalyst 6. As described above, in the reactor according to the present invention, the barrier plate is formed into a mesh, and the contact between the liquid reactant and the solid catalyst that is reacted in the reactor by filling a solid catalyst inside the mesh is activated, and the solid catalyst is isolated by the mesh. There is no need to separate the reactants from the solid catalyst after the reaction is completed. In addition, since the baffle plate is formed of a plurality of baffle plates, preferably 9, as shown in FIG. 2 in the cylindrical reactor, the contact activity of the catalyst and the reactant can be maximized.
또한, 제1도에 나타난 바와 같이 본 발명의 촉매 충진 회분식 반응기(1)의 내부 중심축(3)에는 액상 반응물을 교반하기 위한 교반기(4)가 설치된다. 상기 교반기(4)의 상세한 도면을 제4도에 나타냈다. 제4도에 나타난 바와 같이, 교반기(4)에는 4개의 날개(7)가 설치되고, 상기 날개(7)는 축방향(3)을 따라 일정 간격으로 설치되며, 상기 날개(7)의 길이(L)는 방해판(2) 폭(w)의 6배로 하고, 날개(7)의 두께(8)는 약 3mm로 한다.In addition, as shown in FIG. 1, the inner central axis 3 of the catalyst packed batch reactor 1 of the present invention is provided with an agitator 4 for stirring the liquid phase reactant. The detailed drawing of the said stirrer 4 is shown in FIG. As shown in FIG. 4, the stirrer 4 is provided with four blades 7, the blades 7 are installed at regular intervals along the axial direction 3, and the length of the blades 7 ( L) is 6 times the width w of the baffle plate 2, and the thickness 8 of the blade 7 is about 3 mm.
즉, 본 발명에 의하면, 교반기가 설치되어 상기 방해판 내의 고체 촉매와 액상 반응물의 반응 효과를 균일하고, 활성적으로 일으킬 수 있다.That is, according to the present invention, a stirrer may be provided to uniformly and actively generate a reaction effect of the solid catalyst and the liquid phase reactant in the baffle plate.
상기와 같이 본 발명에 의한 고체 촉매 충진 회분식 반응기는 고체 촉매를 방해판의 그물망 내부에 충전하여 반응기내에서 반응하게 되는 액상반응물과 촉매와의 접촉성을 최대화하고, 또한 고체 촉매가 방해판 내의 그물망 안에 고립되어 있기 때문에 반응이 완결된 후에 촉매 입자와 액상 반응물을 별도로 분리 수거 채집하는 과정이 불필요하여 반응 단계가 매우 간편하게 되어 있으며, 이로 인한 반응 시간의 단축 및 작업 수고가 매우 절약되는 효과를 나타낸다. 또한 상기 반응기의 내부에는 반응을 활발하게 일어나도록 하는 교반기가 설치되어 전동기(도시하지 않음) 등에 의한 수단에 의해 자동적으로 교반기의 회전 속도를 조절하고, 균일하게 교반 속도를 유지할 수 있어서, 반응 효과를 최대로 얻을 수 있도록 하는 효과를 갖는다.The solid catalyst packed batch reactor according to the present invention as described above maximizes the contact between the catalyst and the liquid reactant reacted in the reactor by filling the solid catalyst inside the mesh of the baffle plate, and the solid catalyst is also meshed in the baffle plate. Since it is isolated inside, it is not necessary to separately collect and collect the catalyst particles and the liquid reactants after the reaction is completed, so that the reaction step is very simple, which shortens the reaction time and saves labor. In addition, inside the reactor, a stirrer is provided to actively generate a reaction, and the rotation speed of the stirrer can be automatically adjusted by means of an electric motor (not shown) or the like, and the stirring speed can be maintained uniformly, thereby improving the reaction effect. It has the effect of obtaining maximum.
