Process for catalytic cracking of petroleum hydrocarbons in a fluidized bed with maximized production of light olefins

A process is described for catalytic cracking of hydrocarbon feedstocks from petroleum refining which increases substantially the yields of light olefins. The process limits the extreme conditions to a first reaction section and introduces a stream of cooling fluid above the feedstock injection poin...

Summary:A process is described for catalytic cracking of hydrocarbon feedstocks from petroleum refining which increases substantially the yields of light olefins. The process limits the extreme conditions to a first reaction section and introduces a stream of cooling fluid above the feedstock injection point so as to maintain a second reaction section under cracking conditions which produce light olefins propene and ethene, and inhibits reactions undesirable for the process.
