ABSTRACT:
An endothermic reaction apparatus for converting a raw gas, or a feed gas, into a reaction gas or a produced gas, under the influence of an endothermic reaction catalyst includes a reaction tube having a pair of inner and outer vertical tubular spaces which are separated by a vertical partition wall and communicate with each other at their lower ends. The endothermic reaction catalyst is disposed in the inner and outer tubular spaces to form a continuous catalyst structure. The catalyst structure has an inlet portion for introducing the raw gas into the catalyst structure and an outlet portion for discharging the reaction gas from the catalyst structure. The inlet and outlet portions of the catalyst structure are disposed generally at the same level. A burner is disposed inwardly of the inner tubular space for heating the catalyst structure. The reaction tube is received in a furnace container, and a combustion gas from the burner flows downwardly inwardly of that portion of the inner tubular space containing the catalyst and further flows upwardly outwardly of that portion of the outer tubular space containing the catalyst. A heat-insulating layer is mounted on the partition wall and disposed at least at that portion of the cylindrical partition wall disposed between the inlet and outlet portions of the catalyst structure.
