Hydrocarbon conversion for light gas production

Claim 1

A HYDROCRACKING-HYDROGENATION PROCESS WHICH COMPRISES CONTACTING A HYDROCARBON DISTILLATE FEED BOILING BETWEEN ABOUT 170* AND 320*F. AND HYDROGEN IN A HYDROCRACKING ZONE WITH A HYDROCRACKING CATALYST COMPRISING A HYDROGENATING-DEHYDROGENATING COMPONENT AND AN ACTIVE ACIDIC CRACKING COMPONENT COMPRISING A CONVENTIONAL CRACKING CATALYST AT OPERATING CONDIIONS OF ABOUT 550*750*F., ABOUT 800-1000 P.S.I.G. AND ABOUT 0.3-1.0 LHSV ON A ONCE-THROUGH BASIS THEREBY CONVERTING ABOVE ABOUT 60 PERCENT OF SAID DISTILLTE FEED TO PRODUCTS BOILING BELOW THE C7 BOILING RANGE AND PREDOMINANTLY COMPRISING C3, IC4 AND NC4 HYDROCARBONS, AND CONTACTING THE EFFLUENT FROM SAID HYDROCRACKING ZONE AND AN OLEFINIC FEED SELECTED FROM THE GROUP CONSISTING OF C3-C6 OLEFINS IN A HYDROGENATION ZONE WITH A HYDROGENATION CATALYST CONSISTING ESSENTIALLY OF A HYDROGENATING-DEHYDROGENATING COMPONENT AND A NONACTIVE NON-ACIDIC CRACKING COMPONENT SELECTED FROM THE GROUP CONSISTING OF SILICA, TITANIA, ZIRCONIA, BAUXITE, CHARCOAL AND ALUMINA, AT OPERTING CONDITONS OF ABOUT 500*-775*F., ABOUT 800-1000 P.S.I.G. AND ABOUT 0.1-10 LHSV ON A ONCE-THROUGH BASIS TO CONVERT ABOVE ABOUT 90 PERCENT OF SAID OLEFINIC FEED TO PARAFFINS.
