Abstract

Provided is a reactor in which a catalyst to accelerate reaction of a reactant is allowed to act on a reaction fluid having the reactant. The reactor has a partition that defines, in a parallel form, a plurality of reaction flow passages through which the reaction fluid flows, and a plurality of catalyst structures, each having a catalyst and being respectively provided in each of the plurality of reaction flow passages. The partition has a communicating portion allowing the plurality of reaction flow passages to communicate mutually.

First claim

What is claimed is:

1 . A reactor in which a catalyst to accelerate reaction of a reactant is allowed to act on a reaction fluid having a reactant, the reactor comprising:
a partition that defines, in a parallel form, a plurality of reaction flow passages through which the reaction fluid flows; and a plurality of catalyst structures, each having the catalyst and being respectively provided in each of the plurality of reaction flow passages; wherein the partition has a communicating portion allowing the plurality of reaction flow passages to communicate with each other.

2 . The reactor according to claim 1 , wherein the communicating portion of the partition is arranged so that, in a range from an inlet to an outlet of the reaction flow passage, the plurality of reaction flow passages communicate on the inlet side.

3 . The reactor according to claim 1 , wherein the partition includes one or a plurality of partition walls extending along a flow direction of the reaction fluid, the partition wall is configured to include at least two partial partition walls arranged apart from each other so as to have a gap therebetween, and the communicating portion of the partition has the gap of the partition wall.

4 . The reactor according to claim 1 , wherein the partition includes one or a plurality of partition walls extending along a flow direction of the reaction fluid, and the communicating portion of the partition has a cutout provided in the partition wall.

5 . The reactor according to claim 1 , wherein the partition includes one or a plurality of partition walls extending along a flow direction of the reaction fluid, and the communicating portion of the partition has a through-hole provided in the partition wall.

6 . The reactor according to claim 1 , wherein each of the plurality of catalyst structures includes a main body which divides the reaction flow passage along the flow direction of the reaction fluid and defines a plurality of partial flow passages in parallel, and the main body has a communicating portion allowing the plurality of partial flow passages to communicate with each other in correspondence with the communicating portion of the partition.

7 . The reactor according to claim 6 , wherein the main body is configured to include at least two portions arranged apart from each other so as to have a gap therebetween, and the communicating portion of the main body has the gap of the main body.

8 . The reactor according to claim 6 , wherein the communicating portion of the main body has a cutout provided in the main body.

9 . The reactor according to claim 6 , wherein the communicating portion of the main body has a through-hole provided in the main body.

10 . The reactor according to claim 6 , wherein the main body includes a thin plate material being bent in such a manner to form one or more parallel grooves and ridges, and define each of the plurality of partial flow passages so as to have a rectangular cross section being perpendicular to the flow direction of the reaction fluid, and
the communicating portion of the main body has a cutout provided in at least one of a part forming the groove and a part forming the ridge of the thin plate material.
