ABSTRACT:
An FCC process in which hydrogen produced by water thermolysis adheres to the catalyst and is used in the reaction zone to achieve improved product selectivity and reduced coke production. The catalyst used is a crystalline aluminosilicate cation exchanged with transitional metal cations. The water thermolysis is carried out in the circulating catalyst upstream of the reaction zone at water thermolysis conditions.
