Power Plant With Membrane Water Gas Shift Reactor System

United States Patent Application

View the Complete Application at the US Patent & Trademark Office
The fuel processing system of the present invention supplies a flow of H2-rich reformate to a water gas shift membrane reactor, comprising a water gas shift reaction region and a permeate region, separated by an H2-separation membrane H2 formed over a catalyst in the reaction region selectively passes through the H2-separation membrane to the permeate region for delivery to a use point (such as the fuel cell of a fuel cell power plant) A sweep gas, preferably steam, removes the H2 from the permeate region The direction of sweep gas flow relative to the reformate flow is controlled for H2-separation performance and is used to determine the loading of the catalyst in the reaction region Coolant, thermal and/or pressure control subsystems of the fuel cell power plant may be integrated with the fuel processing system
