  • Compact methanol steam reformer with integrated hydrogen separation
    Patent number: 7115148
    Abstract: Hydrogen is produced in a compact methanol-steam reformer, which integrates an inner cylindrical heating chamber; and a reactant vaporizer and heating zone, and an outer Cu/ZnO/Al2O3 catalyst bed in concentric annuli around the heating chamber. Tubular, palladium-silver alloy membranes in the catalyst bed separate hydrogen from retentate gas, which is separately discharged from the apparatus through a manifold.
    Type: Grant
    Filed: May 13, 2003
    Date of Patent: October 3, 2006
    Assignee: Her Majesty the Queen in right of Canada, as respresented by the Minister of Defence of Her Majesty's Canadian Government

  • Fuel processing system
    Publication number: 20030204993
    Abstract: A method and apparatus for processing a hydrocarbon fuel comprises: a primary fuel processing reactor for converting a feed stream to a first reformate stream comprising hydrogen; a first hydrogen separator located downstream of the primary fuel processing reactor and fluidly connected thereto for receiving the first reformate stream, the first separator comprising a first membrane for separating the first reformate stream into a first hydrogen-rich stream and a first retentate stream; and a secondary fuel processing reactor fluidly connected to the first separator for receiving and converting the first retentate stream to a second reformate stream comprising hydrogen. A fuel cell power generation system includes the present apparatus and a fuel cell stack fluidly connected thereto for receiving hydrogen-rich streams therefrom.
