Blanton, W A; Flanders, R L

Carbon monoxide and sulfur oxides are removed from catalyst regenerator flue gas in an FCC system using a nonzeolitic cracking catalyst. Sulfur from the flue gas is shifted to form hydrogen sulfide, which is recovered in the gases removed from the cracking reactor in the system by reacting carbon monoxide in the regenerator flue gas with oxygen in contact with a particulate carbon monoxide combustion promoter. Sulfur oxides in the regenerator flue gas react with particulate alumina physically mixed with the nonzeolitic catalyst to form a sulfurcontaining solid. Hydrogen sulfide is formed in the cracking reactor by contacting the sulfur-containing solid with the hydrocarbon feed.
