Graven, R G; Sailor, R A

A metal combustion promoter is introduced into the circulating inventory of catalyst in the catalytic cracking process to temporarily change the operating mode of the regenerator and decrease the co content of the flue gas, thus permitting temporary shutdown of the co-boiler of co-incinerator, while continuing operation of the catalytic cracking process. The metal combustion promoters are compounds of platinum, iridium, osmium, palladium, rhodium, ruthenium, or rhenium. The described technique permits rapid shutdown and minimizes the time of operation outside of compliance with local or other ordinances.
