Walkey, J E

An integrated hydrocarbon conversion process is described for converting a heavy hydrocarbon feedstock boiling above 650/sup 0/F into various valuable products including gasoline, jet fuel, and coke steps. Included are: hydrodesulfurizing the feedstock in a hydrodesulfurization zone; catalytically cracking at least a portion of the fraction from the hydrodesulfurization zone boiling in the range of about 650/sup 0/ to about 1000/sup 0/F; feeding at least a portion of the decant oil from the catalytic cracking zone and at least a portion of the fraction from the hydrodesulfurization zone boiling above about 1,000/sup 0/F to a coking zone and coking the mixture; recycling at least a portion of the catalytic cracker cycle oil and the coker gas oil to the hydrodesulfurization zone; and recovering as products of the integrated hydrocarbon conversion process at least gasoline, jet fuel, and coke.
