NOVELTY - A feed gas mixture containing alcohol fuel is contacted with reforming catalyst in reforming reaction zone to form a product reformate gas mixture containing hydrogen. The formed reformate gas mixture and an intake gas mixture containing oxygen are fed to combustion chamber and the intake gas mixture is combusted to produce an exhaust gas mixture. An exhaust gas effluent is discharged from the chamber. The energy of combustion is utilized for generation of mechanical/electrical power. The effluent is thermally contacted with reforming reaction zone to heat catalyst.    USE - For producing mechanical or electrical power from fuel containing alcohol used for vehicular power system.    ADVANTAGE - The alcohol is efficiently reformed to produce hydrogen-containing gas mixture used as fuel.    DETAILED DESCRIPTION - A feed gas mixture containing an alcohol fuel is contacted with a reforming catalyst in a reforming reaction zone to produce a product reformate gas mixture containing hydrogen. The catalyst has a copper coating partially covering the surface of a metal sponge supporting structure, which is obtained by leaching aluminum from an alloy containing aluminum and a base metal. The obtained reformate gas mixture and an intake gas mixture containing oxygen are introduced into a combustion chamber of an internal combustion engine, and the intake gas mixture is combusted to produce an exhaust gas mixture. An exhaust gas effluent containing exhaust gas mixture is discharged from the combustion chamber. The energy of combustion is utilized for generation of mechanical or electrical power. The effluent is thermally contacted with reforming reaction zone to heat the reforming catalyst. Thus, mechanical or electrical power is produced from fuel containing alcohol. The reforming catalyst contains a non-metal supporting structure having carbon, alumina, lanthanum oxide, silica, titania, zirconia, siloxane and/or barium sulfate, and mixture of copper and nickel at the surface of non-metal supporting structure. The metal sponge supporting structure contains copper and/or non-copper metal chosen from nickel, cobalt, zinc, silver, palladium, gold, titanium and iron. Alcohol is methanol and/or ethanol. The product reformate gas mixture contains hydrogen, methane and carbon dioxide component chosen from carbon monoxide and carbon dioxide. An INDEPENDENT CLAIM is included for method for reforming alcohol fuel containing ethanol.    DESCRIPTION OF DRAWING(S) - The figure shows the schematic view of reformed alcohol power system.
