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 sorbent/catalyst. The sorbent/catalyst is selected form the group consisting of silica, alumina, and other Claus-type catalysts, sodium/alumina, zinc ferrite, zinc titanate, and other mixed metal oxides, and mixtures thereof.
