PURPOSE:To reform a hydrocarbon to an inorganic gas consisting essentially of gaseous carbon dioxide without reducing the catalytic activity, by mixing the hydrocarbon with water or air, and passing the resultant mixture through a reforming catalyst of a specific shape consisting of a heat-resistnat inorganic material. CONSTITUTION:A reaction tube 7 is preheated to a given temperature by a heater 9, and the supply of a hydrocarbon is started from a pipe 3 for supplying the hydrocarbon. On the other hand, water or air is supplied from a supply pipe 5 to a path 4. The hydrocarbon gas, steam and air are then passed through inorgnic heat-resistant fibers 6, e.g. quartz wool, mixed, and then fed to an integrally molded reforming catalytic material 8, consisting of a heat-resistant inoragnic material, e.g. alumina or cordierite, and having a cross section consisting of honeycombed or lattice-like multilayered thin walls in which a metal having the catalytic activity, e.g. nickel, cobalt or platinum group metal, is supported on a part of a catalytic carrier or in a concentration distribution all over the carrier and reformed to give an inoragnic gas consisting essentially of hydrogen and gaseous carbon dioxide. |
