HEAT EXCHANGER TYPE REACTION TUBE

摘要

Provided is a heat exchanger type reaction tube that has high thermal uniformity and little heat loss. The heat exchanger type reaction tube comprises: a first tube section (2) forming a first flow channel (4) through which a source gas flows and descends; a second tube section (3) forming a second flow channel (5) which communicates with the first flow channel (4) and which the source gas ascends in, said second tube section (3) being filled with particulate catalyst support bodies; and a heating device for heating the first tube section (2) and the second tube section (3). In addition, the first flow channel (4) and the second flow channel (5) are adjacent with a partition therebetween, and a distribution plate (8) which retains the catalyst support bodies and allows the source gas to pass is provided in the second flow channel (5).
