  • Patent number: 5922291
    Abstract: 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.
