Abstract

A reactor includes: a reaction-side flow passage through which a fluid as a reaction object flows; and a catalyst structure provided in the reaction-side flow passage. The catalyst structure includes: a body part formed in a raised and depressed plate shape to partition the reaction-side flow passage into a plurality of flow passages disposed side by side in a direction perpendicular to a flow direction of the fluid; a catalyst carried on the body part to promote a reaction of the fluid; and one or more communication holes (grooves) to make the plurality of flow passages partitioned by the body part communicate with each other.

First claim

What is claimed is:

1. A reactor, comprising:
a reaction-side flow passage through which a fluid as a reaction object flows; and
a catalyst structure separated from the reaction-side flow passage provided in the reaction-side flow passage,
the catalyst structure including:
a body part formed in a plate shape having two or more raised points and two or more depressed points each alternately provided one by one, the body part partitioning the reaction-side flow passage into a plurality of flow passages disposed side by side in a direction perpendicular to a flow direction of the fluid,
a catalyst carried on the body part to promote a reaction of the fluid, and
communication holes to make the plurality of flow passages partitioned by the body part communicate with each other,
the communication holes comprising at least either: first groove parts each provided on a surface of each of the raised points and between each of the raised points and a wall defining the reaction-side flow passage; or second groove parts each provided on a surface of each of the depressed points and between each of the depressed points and the wall defining the reaction-side flow passage, each extending along the direction perpendicular to the flow direction of the fluid.

2. The reactor according to claim 1 , wherein
the catalyst structure further includes a flat plate in contact with at least one of the raised point and the depressed point in the body part, and
the communication holes further comprise at least either: third groove parts each provided on the flat plate at a point in contact with each of the raised points; or fourth groove parts each provided on the flat plate at a point in contact with each of the depressed points, each extending along the direction perpendicular to the flow direction of the fluid.

3. The reactor according to claim 1 , wherein
the communication hole is a through hole formed in the body part.

4. The reactor according to claim 1 , wherein
a size of the communication hole is smaller than a flow passage cross-sectional area of the flow passage partitioned by the body part.

5. The reactor according to claim 1 , further comprising a temperature controller configured to heat or cool the fluid from an outside of the reaction-side flow passage.

6. The reactor according to claim 5 , wherein
the temperature controller includes a heat-medium-side flow passage through which a heat medium flows to perform heat exchange with the fluid flowing through the reaction-side flow passage, and the heat-medium-side flow passage is provided side by side with the reaction-side flow passage through a heat transfer partition wall.

7. The reactor according to claim 6 , wherein the heat medium is gas.

8. The reactor according to claim 6 , wherein the reaction-side flow passage and the heat-medium-side flow passage are alternately stacked.
