METHOD OF REDUCING QUANTITIES OF CARBON MONOXIDE AND SULFUR OXIDE FROM FLUE GAS AND COMPOSITION CONSISTING OF DECOMPOSITION CATALYST AND GRANULAR SOLID

摘要

PROCESS FOR REMOVING POLLUTANTS FROM CATALYST REGENERATOR FLUE GAS Carbon monoxide and sulfur oxides are removed from flue gas produced in a catalyst regenerator in as FCC system and 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, reacting sulfur oxides in the regenerator flue gas with particulate alumina physically mixed with the FCC catalyst to form a sulfur-containing solid, and forming hydrogen sulfide in the cracking reactor by contacting the sulfur-containing solid with the hydrocarbon feed.
