A CATALYTIC PROCESS FOR TREATING A SULFUR-CONTAINING HYDROCARBON OIL BOILING ESSENTIALLY ABOVE 400* F. WITH HYDROGEN, WHICH COMPRISES PASSING A FEED MIXTURE OF SAID SULFUR-CONTAINING OIL, RECYCLED TREATED OIL AND HYDROGEN DOWNWARDLY THROUGH A REACTION ZONE CONTAINING A BED OF PARTICULATE SULF-ACTIVE HYDROGENATION CATALYST AND MAINTAINED AT A TEMPERATURE IN THE RANGE OF ABOUT 650 TO 850 F. AND AT A PRESSURE IN THE RANGE OF ABOUT 500 T0 3000 P.S.I. G. SO THAT AT LEAST PART OF THE OIL IN SAID MIXTURE REMAINS IN THE LIQUID PHASE AND TRICKLETS DOWN OVER THE SURFACES OF SAID PARTICULATE CATALYST IN SAID BED, AND RECYCLING AT LEAST ABOUT 2 VOLUMES OF TREATED OIL FOR ADMIXTURE WITH EACH VOLUME OF SAID SULFUR-CONTAINING OIL PASSED THROUGH SAID REACTION ZONE.
