ABSTRACT:
A novel cracking catalyst, a method of preparing same and an improved hydrocarbon cracking process are provided wherein adverse effects of metals such as nickel, vanadium, iron, copper and cobalt in the cracking catalyst are precluded or mitigated by contacting the cracking catalyst with an antimony treating agent comprising at least one of elemental antimony and compounds thereof and a lithium treating agent comprising at least one of elemental lithium and compounds thereof whereby there is added to said catalyst a modifying amount of each antimony treating agent and lithium treating agent with the weight ratio of antimonmy to lithium being such as to provide passivation of contaminating metals greater than the sum of the passivation effect of each of antimony treating agent and lithium treating agent individually.
