  • 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.
