ABSTRACT:
A fluid catalytic cracking process and apparatus in which a plurality of hydrocarbon feedstocks including at least one normally gaseous paraffinic hydrocarbon feedstock and at least one normally liquid hydrocarbon feedstock are subjected to cracking reaction conditions in a common transport type reaction zone in the presence of a zeolite cracking catalyst. Fresh hot regenerated catalyst is first contacted with a normally gaseous paraffinic hydrocarbon under dehydrogenation reaction conditions effecting conversion to normally gaseous olefins, and fresh normally liquid cracking charge stock is contacted in the reaction zone under cracking reaction conditions with the gaseous paraffinic and olefinic hydrocarbons.
