Abstract
In a catalytic cracking process which includes contacting a hydrocarbon feedstock in a contacting zone in the presence of solid composition containing molecular sieve-containing catalyst capable of promoting hydrocarbon cracking at conditions effective to crack the hydrocarbon feedstock to lower boiling components, the improvement comprising conducting the contacting in the presence of at least one metal component, other than the catalyst, containing calcium and tin. A composition of matter comprising such catalyst and metal component is also disclosed.
