Method for producing elemental sulfur from sulfur-containing gases

A method for producing elemental sulfur and reduced/oxidizedsulfur compounds from sulfur containing gases. The method comprisesmixing a primary gas stream of sulfur-containing gases with asecondary gas stream to produce a combined gas stream having apreselected stoichiometry and contacting the combined gas streamwith a catalyst at a pressure of 7 to 100 atmospheres and atemperature of 540.degree. to 700.degree. C. The catalyst isselected from the group consisting of silica, titania, alumina,sodium/alumina, zinc titanate, alumina or titania promoted withtransition metals nickel, cobalt, molybdenum, tungsten, alloys andmixtures thereof and mixture of such catalysts.
