Abstract: The present invention involves a catalytic process for purifying a gas stream comprising purifying the gas stream at a temperature from about 250° to 550° C. by removing sulfur compounds and including a gas shift reaction to convert carbon monoxide to carbon dioxide to produce a partially purified gas stream. The warm gas stream purification involves COS hydrolysis and hydrogenation to H2S, the removal of H2S, and a CO gas shift to convert CO to CO2 to produce a partially purified stream. Then the carbon dioxide and other impurities are removed from the partially purified gas stream.

Abstract: A combined process for the recovery of sulfur from an acid gas stream. The combined process includes both a Claus unit and a unit for treating the Claus tail gas with caustic to remove hydrogen sulfide therefrom and to biologically oxidize the hydrogen sulfide using certain types of sulfur bacteria to make elemental sulfur. The combined process provides for an exceptionally low concentration of hydrogen sulfide in the finally treated sweet gas.
