することを特徴とする改質反応装置。 A double-tube reaction system in which a hydrocarbon reforming catalyst is filled into the void formed by the inside of an outer tube and the outside of an inner tube, which are arranged twice in the vertical direction, forming a reforming catalyst layer. The raw material gas to be reformed is supplied from below the reforming catalyst layer, and the reformed gas that has undergone the reforming reaction is turned back at the upper end of the outer tube of the reaction tube, and is returned to the inner side of the inner tube. In an inverted double-tube reforming reactor having a structure in which flow flows downward through the double-tube reaction tube, the outer diameter of the inner tube at the upper end of the double-tube reaction tube is reduced, and the inner wall of the upper end of the outer tube is A reforming reaction device characterized in that it has a structure in which a gap formed between the two is used as a preliminary reforming catalyst filling section.
