ABSTRACT:
A cyclic, fluidized catalytic cracking process providing reduced emissions of noxious effluents in regeneration zone flue gases is operated with regenerable, fluidized, solid particles which are circulated throughout the catalytic cracking process cycle and which comprise (1) a cracking catalyst, (2) a metallic reactant which reacts with a sulfur oxide to form a metal- and sulfur-containing compound in the solid particles, and (3) a metallic oxidation promoter.
