A process is described for removing a sulfur oxide from a gaseous stream containing a sulfur oxide. It comprises the step of contacting the gaseous stream in the presence of a hydrogen donor with a catalyst composition comprising zinc titanate and at least one promoter selected from the group consisting of vanadium, chromium, cobalt, nickel, molybdenum, tungsten, rhenium, platinum, palladium, rhodium, ruthenium and compounds thereof. The sulfur oxide is converted to hydrogen sulfide and the hydrogen sulfide is absorbed by the catalyst composition.
