Abstract:
1. A process for producing hydrogen comprising: decomposing a metal halide compound MX using heat and in the presence of a catalyst so as to reduce the metal M in the metal halide compound MX from an initial valence state to a lower valence state; wherein a gas is formed, thereafter, the gas is reacted with water in the presence of an acid-absorbing material to form oxygen and an acidic compound, the acidic compound being formed by an acid and the acid absorbing material; separating the oxygen; separating the acid from the acid-absorbing material; and reacting the acid and the reduced metal halide to produce hydrogen and the compound MX, wherein the metal halide compound MX is vanadium trichloride, and wherein the catalyst is capable of lowering the decomposition temperature of vanadium trichloride.
