メタノール水蒸気改質用ZnO/CuOナノワイヤ触媒における物質輸送の評価

抄録

ZnO/CuO nanowire (NW) catalysts for steam methanol reforming are prepared and evaluated for hydrogen supply to fuel cells. The NW catalysts are expected to be more durable than conventional nanoparticle catalysts due to their fine structure that prevents agglomeration. The NW catalysts are hydrothermally synthesized on a glass plate and coated with CuO by pyrolysis of an aqueous copper nitrate solution. The reforming tests of a packed bed NW catalysts reformer exhibit the effects of the fuel space velocity and the pulverization of the NW lump on the conversion and mass transport of the fed fuel gas.
