It has become possible to provide a carbon fine particle production method and a production apparatus capable of instantaneously generating carbon fine particles by generating the above.
本発明に従うカーボン微粒子の製造装置を図面を参照しながら説明する。
図1は、本発明の代表的な製造装置のフローチャートを示したものである。
An apparatus for producing fine carbon particles according to the present invention will be described with reference to the drawings.
FIG. 1 shows a flowchart of a typical manufacturing apparatus of the present invention.
図1に示すカーボン微粒子の製造装置1は、バイオマス資源を貯蔵・保管するバイオマス受入槽2と、バイオマス受入槽2からバイオマス資源を装入し、バイオマス資源のCN比(炭素と窒素の原子比)を調整する調整槽3と、調整したバイオマス資源を35〜60℃で加熱してメタンガスを生成するメタン発酵装置4と、該メタン発酵装置4で生成したメタンガスを回収するガスホルダー5と、ガスホルダー5で回収したメタンガス、及び、例えばガスボンベ6内から供給される純酸素又は酸素を富化した空気のような酸素含有ガスの混合割合が異なる2種類の混合ガスを作製し、一方の混合ガスで完全燃焼反応を生じさせて、二酸化炭素と水蒸気を含有する820℃以上の高温混合ガスを生成させる第1反応室7と、この生成した高温混合ガスを加えた他方の混合ガスで不完全燃焼反応を生じさせることによって、カーボン微粒子と水素ガスを瞬時に生成させる第2反応室8と、生成した水素ガスを回収するガスホルダー9とを具えている。
The carbon fine particle production apparatus 1 shown in FIG. 1 has a biomass receiving tank 2 for storing and storing biomass resources, and a biomass resource charged from the biomass receiving tank 2, and the CN ratio of the biomass resources (atomic ratio of carbon and nitrogen). The adjustment tank 3 for adjusting the temperature, the methane fermentation apparatus 4 for generating methane gas by heating the adjusted biomass resources at 35 to 60 ° C., the
調整槽3でバイオマス資源のCN比を調整するのは、その後に行なうメタン発酵装置4でのメタン発酵をしやすくするためであり、必要に応じて、適宜配設する。なお、調整槽でCN比を構成する場合には、前記CN比は、C:Nの原子比で10〜15:1の範囲とするのが好適である。 The reason why the CN ratio of the biomass resource is adjusted in the adjustment tank 3 is to facilitate methane fermentation in the methane fermentation apparatus 4 performed thereafter, and is appropriately arranged as necessary. In addition, when comprising CN ratio with an adjustment tank, it is suitable for the said CN ratio to be the range of 10-15: 1 by the atomic ratio of C: N.
メタン発酵装置4でバイオマス資源を35〜60℃で加熱するのは、35℃未満だとメタン菌が活動しなくなるからであり、60℃を超えるとメタン菌が死滅するからである。尚、メタンガスをより効率良く生成させるには、35〜37℃の中温メタン菌活動温度範囲か、又は、55〜60℃の高温メタン菌活動温度範囲でバイオマス資源を加熱することが好ましい。 The reason why the biomass resource is heated at 35 to 60 ° C. in the methane fermentation apparatus 4 is that if it is less than 35 ° C., the methane bacteria are not activated, and if it exceeds 60 ° C., the methane bacteria are killed. In addition, in order to produce | generate methane gas more efficiently, it is preferable to heat biomass resources in 35-37 degreeC mesophilic methane bacteria activity temperature range or 55-60 degreeC high temperature methane bacteria activity temperature range.
また、第1反応室7内に導入される一方の混合ガスは、完全燃焼反応、すなわち、CH4+2O2→CO2+2H2Oの反応を生じさせて820℃以上の高温ガスを生成するため、前記混合ガスのメタンガスと酸素の混合割合は、モル比で1:2とすることが好適である。 One of the mixed gases introduced into the first reaction chamber 7 generates a high temperature gas of 820 ° C. or more by causing a complete combustion reaction, that is, a reaction of CH 4 + 2O 2 → CO 2 + 2H 2 O. The mixing ratio of methane gas and oxygen in the mixed gas is preferably 1: 2.
さらに、第2反応室8内には、第1反応室7内で生成した二酸化炭素と水蒸気を含有する高温混合ガスを加えて導入される他方の混合ガスは、不完全燃焼反応、すなわち、6CH4+7CO2+O2→10CO+10H2+2CO2+2H2O+C、及び/又は、7CH4+8O2→5CO+5H2+CO2+9H2O+Cの反応を生じさせて、カーボン微粒子(C)と水素ガス(H2)を瞬時に生成するため、前記混合ガスのメタンガスと酸素の混合割合は、前者の反応の場合には、モル比で6:1、後者の反応の場合には、モル比で7:8とすることが好適である。 Further, in the second reaction chamber 8, the other mixed gas introduced by adding the high temperature mixed gas containing carbon dioxide and water vapor generated in the first reaction chamber 7 is an incomplete combustion reaction, that is, 6CH. Reaction of 4 + 7CO 2 + O 2 → 10CO + 10H 2 + 2CO 2 + 2H 2 O + C and / or 7CH 4 + 8O 2 → 5CO + 5H 2 + CO 2 + 9H 2 O + C is caused to generate carbon fine particles (C) and hydrogen gas (H 2 ). In order to generate instantaneously, the mixing ratio of methane gas and oxygen in the mixed gas is 6: 1 in the case of the former reaction and 7: 8 in the case of the latter reaction. Is preferred.
また、第2反応室8内の雰囲気は、0kPa(常圧)〜50kPa、1300〜2500℃の範囲、最適には29kPaで2000℃とすることが、カーボン微粒子を高収率で得るため好ましい。 The atmosphere in the second reaction chamber 8 is preferably in the range of 0 kPa (normal pressure) to 50 kPa, 1300 to 2500 ° C., and optimally 29 kPa to 2000 ° C. in order to obtain carbon fine particles in a high yield.
図2は、第1反応室7内に導入される一方の混合ガスが完全燃焼反応によって生成した高温混合ガスの温度と、この高温混合ガスを第2反応室内に導入し不完全燃焼反応によって生成する、投入したバイオマス資源(原料)1トンあたりのカーボン微粒子(C)の生成量(kg)との関係を示したものである。
図2から、高温混合ガスの温度が820℃以上になると、カーボン微粒子の生成量が急激に増加するのがわかる。
FIG. 2 shows the temperature of a high-temperature mixed gas produced by a complete combustion reaction when one mixed gas introduced into the first reaction chamber 7 is produced by an incomplete combustion reaction when this high-temperature mixed gas is introduced into the second reaction chamber. It shows the relationship with the amount of production (kg) of carbon fine particles (C) per ton of input biomass resource (raw material).
From FIG. 2, it can be seen that when the temperature of the high-temperature mixed gas reaches 820 ° C. or higher, the amount of carbon fine particles generated increases rapidly.
本発明では、上記構成の装置を用いることによって、第2反応室8内に供給されたCH4ガスから瞬時(具体的には1/100秒〜1/500秒)にカーボン微粒子が得られる。 In the present invention, carbon fine particles can be obtained instantaneously (specifically, 1/100 second to 1/500 second) from the CH 4 gas supplied into the second reaction chamber 8 by using the apparatus configured as described above.

次に、この発明に従うカーボン微粒子の製造方法の一例(図1の場合)を説明する。
まず、メタン発酵装置4に、バイオマス資源を装入し35〜60℃で加熱してメタンガスを生成させた後、このメタンガスと酸素含有ガスとの混合割合が異なる2種類の混合ガスを作製する。
Next, an example of the method for producing carbon fine particles according to the present invention (in the case of FIG. 1) will be described.
First, after charging biomass resources into the methane fermentation apparatus 4 and heating at 35 to 60 ° C. to generate methane gas, two types of mixed gases having different mixing ratios of the methane gas and the oxygen-containing gas are produced.
その後、一方の混合ガスを第1反応室7に導入して完全燃焼反応を生じさせて、二酸化炭素と水蒸気を含有する820℃以上の高温混合ガスを生成させる。 Thereafter, one of the mixed gases is introduced into the first reaction chamber 7 to cause a complete combustion reaction, and a high-temperature mixed gas containing carbon dioxide and water vapor at 820 ° C. or higher is generated.
次いで、この生成した高温混合ガスを加えた他方の混合ガスを第2反応室8に導入して不完全燃焼反応を生じさせることによって、カーボン微粒子と水素ガスを瞬時に生成させればよい。 Subsequently, the other mixed gas to which the generated high-temperature mixed gas is added is introduced into the second reaction chamber 8 to cause an incomplete combustion reaction, thereby generating carbon fine particles and hydrogen gas instantaneously.
尚、不完全燃焼反応は、高温混合ガスを加えた他方の混合ガスの他に、5mm以下、好適には1〜5nm以下、最適には2nmの粒径の鉄やコバルトなどの金属又は合金粉末、例えばコバルト−鉄合金やペンタカルボニル鉄を触媒として添加することが、かかる反応を促進する上で好ましい。 The incomplete combustion reaction is a metal or alloy powder such as iron or cobalt having a particle diameter of 5 mm or less, preferably 1 to 5 nm or less, and optimally 2 nm, in addition to the other mixed gas to which the high temperature mixed gas is added. For example, it is preferable to add a cobalt-iron alloy or pentacarbonyl iron as a catalyst in order to accelerate the reaction.
本発明の製造装置(図5)を用いてカーボン微粒子の製造を行なったところ、バイオマス資源(原料)1トンから、200kgのカーボン微粒子(粒径:18〜300nmのナノカーボン粉末)を製造できた。原料として廃棄物等のバイオマス資源を用いているので、原料コストはかからず、よって製造コストが安価であった。 When carbon fine particles were produced using the production apparatus of the present invention (FIG. 5), 200 kg of carbon fine particles (nanocarbon powder having a particle size of 18 to 300 nm) could be produced from 1 ton of biomass resource (raw material). . Since biomass resources such as waste are used as raw materials, raw material costs are not incurred, and thus manufacturing costs are low.
これに対し、アーク放電を利用する従来の製造装置を用いてカーボン微粒子の製造を行なったところ、石油化学燃料1トンに対して、150kgのカーボン微粒子(粒径:18〜300nmのナノカーボン粉末)を製造できた。しかしながら、原料として石油等の石油化学燃料を用いているので、原料コストが高価になり、これに伴って、製造コストも高価になった。 On the other hand, when carbon fine particles were produced using a conventional production apparatus using arc discharge, 150 kg of carbon fine particles (particle size: 18-300 nm nano-carbon powder) for 1 ton of petrochemical fuel. Could be manufactured. However, since a petrochemical fuel such as petroleum is used as a raw material, the raw material cost becomes expensive, and accordingly, the manufacturing cost also becomes expensive.
上述したところは、この発明の実施形態の一例を示したにすぎず、請求の範囲において種々の変更を加えることができる。 The above description is merely an example of the embodiment of the present invention, and various modifications can be made within the scope of the claims.
