A PROCESS FOR TREATING A RESIDUAL HYDROCARBON OIL BOILING ABOVE THE GASOLNE RANGE AND CONTAINING AT LEAST ABOUT 5 PARTS PER MILLION OF EACH OF NIKEL AND VANADIUM AS CONATMINATING METALS, COMRPISING THE STEPS OF CONTACTING SAID HYDROCARBON OIL IN A HYDROGENATION ZONE WITH A HYDROGEN DONOR DILUENT IN THE PROPORTIONS OF ABOUT 0.1 TO 10 VOLUMES OF DILUENT PER VOLUME OF RESIDUAL HYDROCARBON OIL; AT A TEMPERATURE IN THE RANGE OF ABOUT 7001200*F. AND A PRESSURE FROM ABOUT ATMOSPHERIC TO ABOUT 200 P.S.I.G. THEREBY REDUCING PARTIALLY THE CONTENT OF SAID CONTAMINATING METALS BY ABOUT 10 TO 90% AND INCREASING THE HYDROGEN-TO-CARBON RATION OF THE HYDROGENATED EFLUENT, SUBJECTING RESULTING HYDROGENATED BOTTOMS BOILING PRIMARILY ABOVE ABOUT 950*F. AND CONTAINING AT LEAST ABOUT 2 PARTS PER MILLION NICKEL AND AT LEAST ABOUT 3 PARTS PER MILLION VAVADIUM TO SOLVENT DEASPHALTING TO REMOVE ABOUT 30 TO 95% OF SAID METAL CONTAMINANTS AND PRODUCE AND EXTRACT AND RAFFINATE, SAID EXTRACT CONTAINING ABOUT 40
