ABSTRACT:
A method for the simultaneous use of a metals passivation agent and an oxidation promoter in a catalytic cracking system. The oxidation promoter charge is increased an effective amount upon charging the passivation agent at an excessive rate to thereby allow the benefits of both agents to be realized.
