Hydrocarbon cracking process and catalyst for use in same.

摘要

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 barium and at least one other metal selected from chromium, zirconium and tin. A composition of matter comprising such catalyst and metal component particles is also disclosed.
