    摘要: A method for the treatment of a methanol reforming catalyst includes pre-aging the catalyst by baking it out in a dry atmosphere in order thereby to complete its inherent initial loss of volume before the start of the methanol reforming reaction. The method may be used for methanol reforming reactors in fuel-cell-operated motor vehicles.

    摘要: A reforming reactor system for water vapor reforming of methanol in fuel-cell operated motor vehicles has a reactor unit with a catalyst-filled reaction space and a particle filter which is arranged in a reformate gas pipe downstream of the reactor unit. The catalyst material is carried in the reaction space by a sieve below which a metallic nonwoven for catching sieved-out fragments and dust particles of the catalyst fill is situated. The particle filter contains a spun steel wool netting and/or several filter steps serially connected behind one another. The particle filter may be arranged to be exchangeable without interrupting the operation of the system. Specifically, a particle filter which has a filter body which can be changed in a gas-tight manner transversely to the gas flow and/or a cyclone filter can be used which has a closing device for the purpose of an emptying of a particle collecting pot which does not interrupt the operation.

    摘要: A reforming reactor, particularly for the water vapor reforming of methanol, with three serially arranged reactor steps, each of which is charged with a catalyst pellet fill. According to the invention, the center reactor step is maintained at a temperature which is suitable for the reforming reaction, while the two other reactor steps remain unheated. The present invention may be used as a reforming reactor for the water vapor reforming of methanol for the purpose of producing hydrogen in a fuel-cell operated motor vehicle.

    摘要: The invention provides a process for operating a system for water vapor reforming of methanol in which, in a mixture preparation step, a water vapor/methanol mixture is prepared from water and methanol and is introduced into a reforming reactor. According to the invention, the mixing ratio of the water vapor/methanol mixture is adjusted as a function of the load condition and/or load changes of the system so that a CO-concentration is obtained in the reformate which remains constant over the whole load range.
