    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: In a device for providing heating energy to a gas-generating system by means of essentially complete catalytic combustion of a fuel on a suitable catalyst material, heat energy is transferred directly or by means of a heat-conducting medium from the catalytic burner to the gas-generating system. To improve the starting behavior and the exhaust emissions, the device comprises three components that are at least temporarily traversed by fuel, with a cold-start component having an electrical heating device. The central component is preferably designed as a filter press with an integrated heat exchanger. A third, unheated, stage is also provided for residual gas combustion.
