Abstract

A reactor includes: a heat exchange body including a heat medium channel through which the heat medium flows and a reaction channel through which the reaction fluid flows; at least one structured catalyst supporting a catalyst for promoting the reaction of the reaction fluid and removably installed in the reaction channel; and a holding member including an extending part extending in a direction conforming to an extending direction of the reaction channel and capable of engaging with the at least one structured catalyst, and regulating parts provided in the extending part to regulate a movement of the at least one structured catalyst in the extending direction of the extending part, wherein the holding member is inserted and removed with respect to the reaction channel while holding the structured catalyst.

First claim

What is claimed is:

1. A reactor using heat exchange between a heat medium and a reaction fluid to cause a reaction of the reaction fluid to proceed, the reactor comprising:
a heat exchange body including a heat medium channel through which the heat medium flows and a reaction channel through which the reaction fluid flows;
at least one structured catalyst supporting a catalyst for promoting the reaction of the reaction fluid and removably installed in the reaction channel; and
a holding member including an extending part extending in a direction conforming to an extending direction of the reaction channel and capable of engaging with the at least one structured catalyst, and regulating parts provided in the extending part to regulate a movement of the at least one structured catalyst in the extending direction of the extending part, the holding member being inserted and removed with respect to the reaction channel while holding the at least one structured catalyst.

2. The reactor according to claim 1 , wherein the at least one structured catalyst engages with the extending part between a first regulating part of the regulating parts located at a position capable of coming into contact with one side in an extending direction of the at least one structured catalyst and a second regulating part of the regulating parts located at a position capable of coming into contact with another side in the extending direction of the at least one structured catalyst.

3. The reactor according to claim 1 , comprising a plurality of structured catalysts each corresponding to the at least one structured catalyst, wherein the extending part engages with the plural structured catalysts arranged in series.

4. The reactor according to claim 1 , wherein the extending part is a plate-like member, and the regulating parts are projections projecting in a direction intersecting with the extending direction of the extending part.

5. The reactor according to claim 4 , wherein the projections adjacent to each other in the extending direction project in opposite directions.

6. The reactor according to claim 1 , wherein the holding member includes an engaging part provided at least at one end of the extending part in the extending direction and brought into contact with an external part of the reaction channel when the at least one structured catalyst is arranged at a predetermined position in the reaction channel.

7. The reactor according to claim 6 , further comprising a reference member supported by an external part of the reaction channel and brought into contact with the engaging part.

8. The reactor according to claim 7 , wherein the reference member is a stick-like member capable of shifting in a direction different from the extending direction of the reaction channel.

9. The reactor according to claim 7 , wherein the reaction channel includes a plurality of branch channels branched in parallel or in layers, and the reference member is brought into contact with the engaging parts of at least two of the holding members installed in the corresponding branch channels.

10. The reactor according to claim 1 , wherein the at least one structured catalyst is a corrugated plate-like member having a wave-like shape in cross section holding a part of the extending part.
