Hydrogen treatment of hydrocarbons

Claim 1

THE PROCESS FIR HYDROGEN TREATMENT OF A STRAIGHT RUN FUEL OIL DISTILLATE AND A CATAYTICALLY CRACKED GASOLINE BOILING BETWEEN ABOUT 310* AND ABOUT 430*F, AND FOR SIMULTANEOUSLY IMPROVING THE OCTANE NUMBER OF THE CATALYTICALLY CRACKED GASOLINE WHICH COMPRISES CONTACTING A MIXTURE OF HYDROGEN, SAID FUEL OIL DISTILLATE AND SAID CATALYTICALLY CRACKED GASOLINE BOILING BETWEEN ABOUT 310* AND ABOUT 430* F. WITH A COBALT-MOLYBDENUM OXIDE CATALYST COMPOSITED WITH AN ACTIVATED ALUMINA CARRIER AT A TEMPERATURE BETWEEN ABOUT 675* F. AND ABOUT 750* F., AT A PRESSURE BETWEEN ABOUT 500 AND ABOUT 700 P.S.I.G., AT A SPACE VELOCITY BETWEEN ABOUT 2 AND ABOUT 8 LIQUID VOLUMES OF MIXED CHARGE STOCK PER HOUR PER VOLUME OF HYDROGENATION CATALYST, FRACTIONATING THE RESULTANT HYDROCARBON MIXTURE TO SEPARATE AN IMPROVED FUEL OIL FRACTION AND A GASOLINE FRACTION HAVING A HIGHER OCTANE NUMBER AND BOILING BETWEEN ABOUT 310* AND 430* F. AND BLENDING THIS LAST MENTIONED GASOLINE FRACTION WITH A LOWER BOILING POINT GASOLINE TO OBTAIN A FINISHED GASOLINE PRODUCT.
