A first aspect of the catalytic reaction apparatus according to the present invention includes a first catalyst, a catalyst support, a second catalyst, and a powder discharger. The first catalyst is granular having a predetermined particle diameter and is provided on the supply side. The catalyst support has pores smaller than the particle size and supports the first catalyst. The second catalyst is located on the side opposite to the first catalyst with respect to the catalyst support and is provided on the exhaust side. The powder discharge unit is provided between the second catalyst and the catalyst support and discharges powder having a particle diameter smaller than that of the holes. The powder discharge section includes a tube extending in a direction having a vertical component and a collection section. The upper side of the pipe communicates with the exhaust side, and the lower side communicates with the supply side via the collecting section.
A second aspect of the catalytic reaction apparatus according to the present invention includes a first catalyst, a catalyst support, a second catalyst, and a powder discharger. The first catalyst is granular having a predetermined particle diameter and is provided on the supply side. The catalyst support has pores smaller than the particle size and supports the first catalyst. The second catalyst is located on the side opposite to the first catalyst with respect to the catalyst support and is provided on the exhaust side. The powder discharge unit is provided between the second catalyst and the catalyst support and discharges powder having a particle diameter smaller than that of the holes. The powder discharge section includes a partition that is non-parallel to a direction from the supply side to the exhaust side and extends in a direction having a vertical component. The partition guides the flowing direction of the powder downward.
A third aspect of the catalytic reaction apparatus according to the present invention includes a first catalyst, a catalyst support, a second catalyst, a powder discharge part, and a filter. The first catalyst is granular having a predetermined particle diameter and is provided on the supply side. The catalyst support has pores smaller than the particle size and supports the first catalyst. The second catalyst is located on the side opposite to the first catalyst with respect to the catalyst support and is provided on the exhaust side. The powder discharge unit is provided between the second catalyst and the catalyst support and discharges powder having a particle diameter smaller than that of the holes. The powder discharge unit includes a first opening that is supplied from below and communicates with the supply side, a second opening that communicates with the discharge side, and a collection unit. The filter is provided on the second opening side in the powder discharge portion, and prevents the passage of the powder. The collection unit is provided on the first opening side with respect to the filter and at the lower side of the filter with respect to the vertical direction so as to open on the filter side.
この発明にかかる触媒反応装置の第１乃至第３の態様によれば、原料ガスが供給側から供給されて、第１触媒で反応する。反応ガスは、触媒支持体及び粉体排出部を通って、第２触媒へと流入する。触媒支持体は、粒状の第１触媒が移動することを防止する。粉体排出部は、第１触媒が破砕等して生じた触媒粉が、反応ガスと共に第２触媒側へと流れることを防止する。よって、第１触媒若しくはその触媒粉が、第２触媒に至るまでの領域及び第２触媒の領域で反応ガスに悪影響を与えることを回避できる。しかも、触媒粉を捕集するためのフィルタを設けなくてもよいので、メンテナンスの必要性が低減される。
According to the 1st thru | or 3rd aspect of the catalyst reaction apparatus concerning this invention, source gas is supplied from the supply side and it reacts with a 1st catalyst. The reaction gas flows into the second catalyst through the catalyst support and the powder discharge part. The catalyst support prevents the granular first catalyst from moving. The powder discharge part prevents the catalyst powder generated by crushing the first catalyst or the like from flowing to the second catalyst side together with the reaction gas. Therefore, it can be avoided that the first catalyst or the catalyst powder adversely affects the reaction gas in the region up to the second catalyst and the region of the second catalyst. Moreover, since it is not necessary to provide a filter for collecting the catalyst powder, the need for maintenance is reduced.
