Abstract
An integrated catalytic fluid coking and gasification process is provided in which a portion of the coke produced in the coker is steam gasified to produce a hydrogen-containing gas and a catalytic partially gasified coke. Subsequently, a portion of the catalytic partially gasified coke is burned to provide heated partially gasified coke which is recycled to the gasification zone. A portion of the catalytic partially gasified coke is passed from the gasification zone to the coker to contact the coker vapor phase product comprising normally liquid hydrocarbons and to crack at least a portion of the normally liquid hydrocarbons. Optionally, solid fines recovered from the gaseous effluent of the gasification zone may be recycled to the carbonaceous chargestock of the coker.
