Abstract
Catalyst stripping in the fluid catalytic cracking process is improved by cooling the spent catalyst to quench catalytic condensation reactions, then stripping the cooled catalyst in a primary stripper, followed by heating and a stage of hot stripping. Quenched stripping reduces coke make by reducing conversion of light olefins, made during the FCC process, into coke.
