Process for the Production of Hydrogen from Hydrogen Sulfide (Technology #: 052200-01)

A process is provided for the production of hydrogen from hydrogen sulfide by reacting carbon monoxide with hydrogen sulfide to produce hydrogen and carbonyl sulfide, and then reacting the carbonyl sulfide with oxygen to produce carbon monoxide and sulfur dioxide. The carbon monoxide is recycled back to the hydrogen sulfide reaction step. The catalyst used to promote the reaction between carbonyl sulfide and oxygen is an oxide of a metal, such as V, Nb, Mo, Cr, Re, Ti, W, Mn or Ta, which is supported on a support, such as TiO.sub.2, ZrO.sub.2, CeO.sub.2, Nb.sub.2 O.sub.5 and Al.sub.2 O.sub.3.
