Abstract

A method for producing elemental sulfur and reduced/oxidized sulfur compounds from sulfur containing gases. The method comprises mixing a primary gas stream of sulfur-containing gases with a secondary gas stream to produce a combined gas stream having a preselected stoichiometry and contacting the combined gas stream with a catalyst at a pressure of 7 to 100 atmospheres and a temperature of 540.degree. to 700.degree. C. The catalyst is selected from the group consisting of silica, titania, alumina, sodium/alumina, zinc titanate, alumina or titania promoted with transition metals nickel, cobalt, molybdenum, tungsten, alloys and mixtures thereof and mixture of such catalysts.
