HEAT EXCHANGER TYPE REACTION TUBE

摘要

Provided is a heat exchanger type reaction tube having high uniformity and small heat loss. The heat exchanger type reaction tube includes: a first tube part (2) that forms a first flow channel (4) into which a feed gas flows and in which the feed gas moves down; a second tube part (3) that forms a second flow channel (5) which is connected to the first flow channel (4) and in which the feed gas moves up and that has a granular catalyst carrying support medium charged therein; and a heating device that heats the first tube part (2) and the second tube part (3). Then, the first flow channel (4) and the second flow channel (5) are adjacent to each other while being separated from each other by a partition wall, and the second flow channel (5) is provided with a distributor (8) which holds the catalyst carrying support medium and through which the feed gas passes.
