Production of high quality jet fuels by two-stage hydrogenation

Abstract

Abstract PROCESS OF PRODUCING A JET FUEL HAVING A LUMINOMETER NUMBER OF AT LEAST 75 COMPRISES CONTACTING A CHARGE COMPRISING JET FUEL RANGE DISTILLATE FROM COKED (THERMALLY RACKED) TAR SANDS BITUMEN (SUCH AS THAT SEPARATED FROM ATHABASCA TAR SANDS BY THE HOT WATER PROCESS) OR A STRIGHT-RUN KEROSENE CHARGE, OR A CATALYTIC GAS OIL CHARGE, ACYCLIC C9-C18 OLEFIN CHARGE (OR A MIXTURE OF AT LEAST TWO SUCH CHARGES) WITH HYDROGEN IN THE PRESENCE OF A HYDROGENATION CATALYST FORMED FROM AT LEAST ONE MEMBER SELECTED FROM THE GROUP CONSISTING OF NICKEL, COBALT, IRON, MOLYBDENUM AND TUNGSTEN AND OXIDES AND SULFIDES THEREOF, ON AN INERT POROUS CARRIER, AT A TEMPERATURE OF 500785*F., A PRESSURE OF 350-2000 P.S.I.G., A LIQUID HOURLY SPACE VELOCITY OF 0.5-10.0 AND A HYDROGEN CIRCULATION RATE OF 0 TO 20,000 S.C.F. PER BARREL OF SAID CHARGE, CONTACTING THE RESULTANT PRODUCT WITH HYDROGEN IN THE PRESENCE OF A CATALYST WHICH COMPRISES A METAL SELECTED FROM THE GROUP CONSISTING OF NICKEL, COBALT, TUNGSTEN, RU, RH, RE, OS AND THE NOBLE METAL HYDROGENATION CATALYSTS (PT AND PD), SAID CATALYST BEING SUPPORTED ON A POROUS SUPPORT (E.G., ALUMINA, KIESELGUHR) AT A TEMPERATURE OF 450-775* F., AT A PRESSURE OF 500-3000 P.S.I.G., A LIQUID HOURLY SPACE VELOCITY OF 0.1-10.0 AND A HYDROGEN CIRCULATION RATE OF 0-20,000 STANDARD CUBIC FEET PER BARREL OF SAID PRODUCT OF THE FIRST STAGE, THE COMBINATION OF CONDITIONS BEING SELECTED TO PRODUCE A JET FUEL HAVING AN ASTM SMOKE POINT OF AT LEAST 32$3.
