A study of methanol steam reforming (MSR) in the presence of a Ni-0.2-Cu-0.8/Ce0.3Zr0.7O2-delta catalyst in conventional and membrane reactors has revealed that the hydrogen yield in a reactor with a Pd-Cu membrane is higher than that in a conventional flow reactor. It has been shown that the Pd-Cu alloy membrane exhibits high hydrogen permeability. Methanol steam reforming in the membrane reactor provides the production of high-purity hydrogen, because a stream of pure hydrogen free from any impurities is effluent from the permeate zone. Measurements of the hydrogen permeability of the Pd-Cu alloy foil membrane in the membrane reactor before and after catalysis have been conducted.
