HYDROGEN MANUFACTURING APPARATUS

PURPOSE: To provide a hydrogen manufacturing apparatus capable of performing the reactions conventionally carried out in a reformer, a carbon monoxide transformer and a hydrogen purifier, at once in a group and producing hydrogen of high purity by freely controlling the temperature of a catalyst layer tank packed with a reforming catalyst. CONSTITUTION: This hydrogen manufacturing apparatus is composed of a vertical burner 1, a cylindrical radiation board 2 surrounding the burner 1 with a space for an air passage 3A between the outer periphery of the burner and itself and forming a burning section 15 having an opening 3B at the upper side, an inner tube 4 surrounding the outer periphery of the radiation board, having a ceiling board 5 between the radiation board and itself and forming a closed reaction section 11 there, an outer tube 9 closely covering the outside of the ceiling board and the inner tube, and forming a burning gas passage 14 communicating with the burning section, plural hydrogen permeating tubes 6 placed in the reaction section and having a closed upper end, plural offgas tubes 10 placed in the reaction section and having an open upper end, and plural sweep gas tubes 7 placed in the hydrogen permeating tube and having an open upper end. A reforming catalyst 13 is packed in the reaction section.
