Title:
FLUID CATALYTIC CRACKING METHOD
Document Type and Number:
Japanese Patent JPS6384632
Kind Code:
A
Abstract:
A catalytic cracking process operates with fragment generation, by thermally or catalytically cracking a hydrogen-rich hydrocarbon feed in the lower region of a riser reactor in the presence of conventional FCC catalyst and, preferably, an additive second catalyst of a shape selective zeolite with heavy feed added to react with the fragments. The process can be conducted in one or more riser FCC reactors. Preferably, an elutriable catalyst mixture of conventional and additive catalyst is used, with elutriation in a reactor riser or a catalyst stripper.
