INTEGRATED CATALYTIC CRACKING AND OLEFIN PRODUCING PROCESS

摘要

Disclosed is a method which combines catalytic cracking and olefin production using a coked catalytic cracking catalyst as a dehydrogenation catalyst to dehydrogenate an alkane feed stream and form an olefin rich product stream. Preferably, the dehydrogenation catalytic cracking catalyst is a combination of spent catalytic cracking catalyst and regenerated catalytic cracking catalyst having an overall carbon content of about 0.2-5.0 wt %. The catalyst preferably comprises a crystalline tetrahedral framework oxide component.
