1. A PROCESS FOR THE HYDROGENOLYSIS OF A HEAVY RESIDUUM HYDROCARBON OIL CONTAINING BOTH PARAFFINS AND AROMATICS, WHICH COMPRISES EXTRACTING A HEAVY HYDROCARBON OIL WITH A SOLVENT WHICH SELECTIVELY DISSOLVES AROMATICS, PASSING THE PARAFFIN RAFFINATE TO A HYDROGENOLYSIS PROCESS WHERE IT IS TREATED AT A TEMPERATURE IN THE RANGE OF 850 TO 900* F., A PRESSURE IN THE RANGE OF 3500 TO 5000 P.S.I., A FEED RATE OF 0.5 TO 4 LIQUID VOLUMES OF CHARGE PER VOLUME OF CATALYST PER HOUR, AND WITH A HYDROGEN CIRCULATION OF 5000 TO 20,000 CUBIC FEET PER BARREL OF FEED, SEPARATING THE PRODUCTS OF THIS HYDROGENOLYSIS AND RECOVERING GASOLINE HAVING AN END BOILING POINT OF 400* F. AND A GOOD QUALITY GAS OIL; SEPARATING THE SOLVENT FROM SAID AROMATICS, PASSING THE AROMATIC EXTRACT TO A HYDROGENOLYSIS PROCESS WHERE IT IS TREATED AT DIFFERENT CONDITIONS AT A TEMPERATURE IN THE RANGE OF 900* F., A PRESSURE ON THE RANGE OF 2000 TO 4000 P.S.I., A FEED RATE OF 0.5 TO 4 LIQUID VOLUMES OF CHARGE PER VOLUME OF CATALYST PER HOUR, AND WITH A HYDROGEN CIRCULATION RATE IN THE RANGE OF 5,000 TO 10,000 CUBIC FEET PER BARREL OF FEED, SEPARATING THE PRODUCTS OF THIS SECOND HYDROGENOLYSIS AND RECOVERING A GOOD QUALITY GASOLINE, AND RECYCLING THE GASOLINE BOILING RANGE MATERIALS FROM THE PARAFFIN HYDROGENOLYSIS PRODUCT TO SAID EXTRACTION AS A SOLVENT FOR PARAFFINS.
