Abstract

A catalytic reactor includes: a reaction-side flow channel in which a reaction fluid flows; structured catalysts accommodated in the reaction-side flow channel. Each structured catalyst includes inclined surfaces in at least part of each of two surfaces facing other structured catalysts. The inclined surfaces are inclined in the same direction with respect to an arrangement direction of the structured catalysts.

First claim

What is claimed is:

1. A catalytic reactor comprising:
a reaction-side flow channel in which a reaction fluid flows, extending in an extending direction defining a flow direction of the reaction fluid; and
a first structured catalyst and a second structured catalyst located in the reaction-side flow channel and arranged in the extending direction of the reaction-side flow channel; wherein
the first structured catalyst includes a first inclined surface in at least part of a surface of the first structured catalyst facing the second structured catalyst,
the second structured catalyst includes a second inclined surface facing the first inclined surface, in at least part of a surface of the second structured catalyst facing the first structured catalyst,
the first inclined surface and the second inclined surface are inclined in the same direction with respect to an arrangement direction of the first structured catalyst and the second structured catalyst,
the first structured catalyst and the second structured catalyst are tilted in the same direction with respect to the arrangement direction in a state where at least part of the first inclined surface and at least part of the second inclined surface are in contact with each other, and
the first and second structured catalysts include a corrugated plate on which a catalyst is carried.

2. The catalytic reactor according to claim 1 , wherein
the first inclined surface is formed in the entire surface of the first structured catalyst facing the second structured catalyst, and
the second inclined surface is formed in the entire surface of the second structured catalyst facing the first structured catalyst.

3. The catalytic reactor according to claim 1 , wherein
the inner surface of the reaction-side flow channel is provided with a protrusion or a step configured to contact an end of the first inclined surface or an end of the second inclined surface.

4. The catalytic reactor according to claim 2 , wherein
the inner surface of the reaction-side flow channel is provided with a protrusion or a step configured to contact an end of the first inclined surface or an end of the second inclined surface.

5. The catalytic reactor according to claim 1 , wherein
an inclination angle of the first inclined surface with respect to the arrangement direction and an inclination angle of the second inclined surface with respect to the arrangement direction are different from each other.

6. The catalytic reactor according to claim 1 , wherein
the first inclined surface is formed in only part of the surface of the first structured catalyst facing the second structured catalyst, and
the second inclined surface is formed in only part of the surface of the second structured catalyst facing the first structured catalyst.

7. The catalytic reactor according to claim 1 , wherein
the second inclined surface is formed in the entire surface of the second structured catalyst facing the first structured catalyst, and
the first inclined surface is formed in only part of the surface of the first structured catalyst facing the second structured catalyst, the only part being in contact with the second inclined surface on a tip side of the second structured catalyst.

8. The catalytic reactor according to claim 1 , wherein
the first and second structured catalysts are tilted to close a clearance between the first and second structured catalysts and an inner surface of the reaction-side flow channel.
