Title: Trace desulfurization. [DOE patent application]

Abstract

A method for reducing a trace concentration of sulfur-containing compounds in a gas stream from about one part in 10/sup 4/ to about one part in 10/sup 7/. The method includes the steps of irradiating the gas stream with an energy source which has a central emission frequency chosen to substantially match a wavelength of energy absorption of the sulfur-containing compounds and of subsequently contacting the gas stream with a reactive surface which includes a reactant selected from elemental metals and metal oxides so that metallic sulfur-containing compounds are formed. The reduction in concentration allows the gas stream to be processed in certain reactions having catalysts which would otherwise be poisoned by the sulfur-containing compounds.
