Gaseous sulfur compounds are removed from a sulfur-containing gas mixture by reacting sulfur oxides in the gas mixture with alumina in association with bismuth. The process is particularly useful in fluid catalytic cracking of sulfur-containing petroleum charge stocks wherein sulfur is contained in coke deposited on the fluidized cracking catalyst. By the process of this invention, sulfur oxides may be removed from regenerator off-gases from a fluidized catalytic cracking unit by incorporating particulate alumina impregnated with bismuth in particulate cracking catalyst whereby sulfur oxides generated in the regeneration of the catalyst are reacted with bismuth-impregnated alumina. Sulfur oxides produced during regeneration of the catalyst by burning the coke with air are captured and converted to hydrogen sulfide in the cracking reactor. The hydrogen sulfide so produced is readily separated from petroleum products of the catalytic cracking reaction process.

An active alumina composite and a cracking catalyst comprising the composite useful in hydrocarbon conversion processes. The composite and catalyst are particularly useful in fluid catalytic cracking processes, wherein sulfur-containing feedstock is subjected to catalytic conversion at a temperature in the range of about 800. degree. F. to about 1300. degree. F. in the presence of the catalyst which becomes sulfided during the conversion reaction and thereafter the catalyst is subjected to regeneration by burning sulfur-containing coke from the catalyst with an oxygen-containing gas at a temperature within the range of about 800. degree. to 1500. degree. F. The novel catalyst composition comprises 90 to 99 weight percent cracking catalyst and 1 to 10 weight percent of a composite of alumina and bismuth oxides containing 0. 05 to 25 weight percent bismuth, calculated as the metal. This catalyst composition has the ability to remove sulfur oxides from gases to a greater extent than catalyst compositions comprising cracking catalyst and active alumina.
