A PROCESS FOR THE PRODUCTION OF A HYDROCARBON FRACTION OF REDUCED SULFUR CONTENT WHICH COMPRISES PASSING A MIXTURE OF A SULFUR-CONTAINING NORMALLY LIQUID HYDROCARBON FRACTION AND HYDROGEN THROUGH A FIRST REACTION ZONE AT A TEMPERATURE BETWEEN ABOUT 850 AND 1500*F., A PRESSURE BETWEEN 1000 AND 20,000 P.S.I.G. AND UNDER CONDITIONS OF HIGHLY TURBULENT FLOW, SAID MIXTURE CONTAINING BETWEEN 4000 AND 100,000 CU.FT. OF HYDROGENATING GAS PER BBL. OF LIQLUID HYDROCARBON, AND CONTACTING AT LEAST A PORTION OF THE REACTION PRODUCT IN A SECOND REACTION ZONE WITH A DESULFURIZATION CATALYST AT A TEMPERATURE BETWEEN 500 AND 1000*F. AND A PRESSURE BETWEEN ATMOSPHERIC AND 2000 P.S.I.G. IN THE PRESENCE OF HYDROGEN
