ABSTRACT:
An integrated hydrocarbon conversion process for the production of low sulfur fuels utilizing a hydrocracking zone, a diesel hydrodesulfurization zone, a fluid catalytic cracking zone and a gasoline hydrodesulfurization zone. The hydrocracking zone is used to convert at least a portion of the feedstock into diesel boiling range hydrocarbons which are desulfurized in the first hydrodesulfurization zone. The unconverted feedstock is introduced into a fluid catalytic cracking zone to produce gasoline boiling range hydrocarbons which are desulfurized in a second hydrodesulfurization zone.
