Abstract
A process for removing hydrogen sulfide from geothermal steam comprising adding free oxygen to the steam and contacting the steam with an oxidation catalyst at a pressure of at least 30 psig and a temperature not greater than the saturation temperature of the steam. The catalyst may comprise activated carbon, a refractory inorganic oxide or a metal phthalocyanine and is wetted with an aqueous solution of thiosulfates, sulfates or polysulfides. The hydrogen sulfide is converted and steam of reduced hydrogen sulfide content is obtained.
