Abstract

A reactor includes first heat transfer bodies including reaction flow channels through which a reaction fluid flows, second heat transfer bodies stacked on the first heat transfer bodies and including heat medium flow channels through which a heat medium flows and product flow channels through which a product flows that is produced in the reaction flow channels by a heat exchange between the reaction fluid and the heat medium, and product communication parts including communication spaces through which the product flows from the reaction flow channels to the product flow channels.

First claim

What is claimed is:

1. A reactor comprising:
a first heat transfer body including a reaction flow channel through which a reaction fluid flows;
a second heat transfer body stacked on the first heat transfer body, and including a heat medium flow channel through which a heat medium flows and a product flow channel through which a product flows that is produced in the reaction flow channel by a heat exchange between the reaction fluid and the heat medium; and
a product communication part including a communication space through which the product flows from the reaction flow channel to the product flow channel.

2. The reactor according to claim 1 , wherein:
the reaction flow channel includes a plurality of main flow parts; and
the product flow channel includes at least one main flow part with a number fewer than a number of the main flow parts in the reaction flow channel.

3. The reactor according to claim 1 , wherein at least one main flow part in the product flow channel is located closer to a side surface of the second heat transfer body than at least one main flow part in the heat medium flow channel in a direction in which the respective main flow parts are arranged parallel to each other.

4. The reactor according to claim 3 , wherein:
the heat medium flow channel includes a plurality of the main flow parts; and
the product flow channel includes at least one main flow part with a number fewer than a number of the main flow parts in the heat medium flow channel.

5. The reactor according to claim 1 , wherein the product flow channel is arranged parallel to the heat medium flow channel.

6. The reactor according to claim 1 , wherein an opening on an inlet side of the product flow channel is open in a direction common to an opening on an outlet side of the reaction flow channel.

7. The reactor according to claim 6 , wherein the opening on the inlet side of the product flow channel is aligned in a line common to the opening on the outlet side of the reaction flow channel in a stacked direction of the first heat transfer body and the second heat transfer body.

8. The reactor according to claim 6 , wherein a part of an inner wall of the product communication part includes a part of a side surface of the first heat transfer body including the opening on the outlet side of the reaction flow channel and a part of a side surface of the second heat transfer body including the opening on the inlet side of the product flow channel.

9. The reactor according to claim 6 , wherein an opening on an outlet side of the product flow channel is open in a direction common to the opening on the inlet side of the product flow channel.
