    摘要: A process for operating a methanol reforming system in which, in the reforming reaction operation, methanol is reformed in a methanol reforming reactor using a methanol reforming catalyst. The reforming reaction operation is interrupted periodically for catalyst reactivation phases during which the methanol reforming catalyst whose catalytic activity decreases in the reforming reaction operation is treated in an activity-regenerating manner. The process may be used in fuel-cell-driven motor vehicles for generating hydrogen for the fuel cells from methanol carried along in the liquid state.

    摘要: A methanol reforming reactor includes a reforming reaction space into which a methanol reforming catalyst is charged. The methanol reforming catalyst is present at the start of the reforming reaction operation in a pre-aged state in the reforming reaction space. A process for pre-aging the methanol reforming catalyst comprises heating at a temperature of between approximately 240° C. and approximately 350° C. and at a load of between approximately 0.5 m3H2/h and approximately 50 m3H2/h per liter of catalyst material in a methanol/water atmosphere. The reactor may be used in fuel-cell-operated motor vehicles for generating hydrogen for the fuel cells by means of the water vapor reforming of methanol.
