摘要：
A three stage catalytic cracking process capable of converting high molecular weight hydrocarbons containing catalyst poisons into products of lower molecular weight by cascading catalyst from a fluid catalytic cracking unit to a reduced crude conversion unit to a metals removal unit is disclosed. Efficiencies in conversion operations are made possible.
