CRACKING SYSTEM AND PROCESS INTEGRATING HYDROCRACKING AND FLUIDIZED CATALYTIC CRACKING

摘要

A system and method of cracking hydrocarbon feedstocks is provided that allows for significant flexibility in terms of the desired product yield. An integrated process includes introducing the feedstock and hydrogen into a first hydro cracking reaction zone containing a first hydro cracking catalyst to produce a first zone effluent. The first zone effluent and optionally additional hydrogen are passed to a second hydro cracking reaction zone containing a second hydro cracking catalyst to produce a second zone effluent. The bottoms fraction is passed to a fluidized catalytic cracking reaction and separation zone, from which olefins and gasoline are recovered.
