ABSTRACT:
A method for regenerating a coke-contaminated cracking catalyst with the simultaneous carefully controlled combustion of CO to CO.sub.2 within a regeneration zone to produce regenerated catalyst and flue gas. Novel features of the method include adding to the regeneration zone, independently of the cracking catalyst, a liquid comprising a soluble CO oxidation promoter selected from the group consisting of the noble metals and compounds thereof and combusting CO to CO.sub.2 in the presence of the promoter and regenerated catalyst. The liquid may be added to the regeneration zone in amounts to control the CO concentration in the flue gas, a regeneration zone temperature, or the residual carbon concentration on regenerated catalyst.
