PURPOSE:To simultaneously impart a heat-transter function and a catalytic function at the time of reforming methanol to produce a hydrogen-contg. gas by depositing a copper-coated nickel oxide catalyst in a heat-transter tube. CONSTITUTION:The metal such as Fe, Cu, Al, Zn, Co and Ni or their alloyed material (heat-transfer tube is preferable) is coated by thermal spraying with the Ni oxide coated with copper by plating, vapor deposition, etc. A gas contg. 3-100% H2 is passed through the material at 200-300 deg.C to reduce the Ni oxide, and a catalyst bed is formed. Methanol or water-contg. methanol is brought into contact with the bed and reformed to produce a hydrogen-contg. gas (contg. >=50% H2, <=35% CO and <=25% CO2). The reaction temp. is controlled to 200-700 deg.C or preferably to 300-600 deg.C, the reaction pressure is adjusted to 0-30kg/ cm<2>G or preferably to 0-15kg/cm<2>G, and the molar ratio of the supplied water to methanol is controlled to <=10 or preferably to <=5. |
