Abstract: A process for producing high octane low lead content or unleaded gasoline from a hydrocarbon feedstock by hydrocracking the hydrocarbon feedstock; fractionating the hydrocracking effluent in a fractionation zone, thereby obtaining a stream rich in singly branched hexanes; isomerizing the singly branched hexanes to doubly branched hexanes in an isomerization zone operated at a reaction temperature below 300.degree.F.; and combining the doubly branched hexanes with C.sub.7 + hydrocarbons derived from the hydrocracking effluent, thereby obtaining a high octane gasoline or gasoline blending stock. In a preferred embodiment, the isomerization zone effluent is fractionated to give a cyclohexane-rich stream which stream is catalytically reformed and then the reformate is combined with the doubly branched hexanes from the isomerization zone.

Abstract: An integrated refinery process for the production of a high octane gasoline pool. The invention essentially comprises a combination low severity reforming zone, aromatic separation means and a saturate cracking zone. The low severity reforming zone effects the production of high octane aromatic components without an accompanying loss in liquid yield from excessive dehydrocyclization and cracking reactions, the aromatic separation means effects the concentration of aromatics from the reformate and a recycle stream from the saturate cracking zone, while the saturate cracking zone cracks the unreacted saturates passing through the reforming zone to effect production of high octane precursors such as low molecular weight olefins and a cracked gasoline component.

Abstract: A LIGHT LUBE SUITABLE FOR USE AS A TRACTION FLUID IS PREPARED FROM A GAS OIL BY HYDROCRACKING. THE PROCESS INVOLVES TREATING THE GAS OIL OVER A CATALYST SUCH AS SUPPORTED NICKEL-MOLYBDENUM, AT FROM 680 TO 780* F. AND 800 TO 2000 P.S.I.G. IN THE PRESENCE OF HYDROGEN TO CONVERT THE SULFUR PRESENT TO HYDROGEN SULFIDE AND THE NITROGEN PRESENT TO AMMONIA. THE GAS OIL IS THEN HYDROCRACKED USING MAGNESIUM ZEOLITE Y CONTAINING 0.2 TO 2.0 WEIGHT PERCENT OF A NOBLE METAL AT FROM 680 TO 780* F. AND FROM 800 TO 2000 P.S.I.G. THE RESULTING HYDROCRACKATE IS WATER WASHED TO REMOVE THE HYDROGEN SULFIDE AND AMMONIA. THE PORTION OF THE HYDROCRACKING BOILING BELOW 650-750* F. IS

RECYCLED TO THE HYDROCRACKER. THE HIGHER BOILING PORTION OF THE HYDROCRACKATE IS DEWAXED TO PRODUCE THE HYDROCRACKED LUBE PRODUCT, USEFUL AS A TRACTION FLUID.
