Hydrofining-hydrocracking process using palladium-containing catalyst

Abstract

Abstract A HYDROFINING-HYDROCRACKING PROCESS WHICH COMPRISES CONTACTING A HYDROCARBON FEED CONTAINING MORE THAN 50 PARTS PER MILLION OF ORGANIC NITROGEN AND CONTAINING SUBSTANTIAL AMOUNTS OF MATERIALS BOILING ABOVE 200* F., SAID FEED BEING SELECTED FROM THE GROUP CONSISTING OF PETROLEUM DISTILLATES, SOLVENT-DEASPHALTED PETROLEUM RESIDUA, SHALE OILS AND COAL TAR DISTALLATES, IN A REACTION ZONE WITH HYDROGEN AND A CATALYST, AT HYDROFINING-HYDROCRACKING CONDITIONS INCLUDING A TEMPERATURE IN THE RANGE 400* TO 950* F., A PRESSURE IN THE RANGE 800 TO 3500 P.S.I.G., A LIQUID HOURLY SPACE VELOCITY IN THE RANGE 0.1 TO 5.0, AND A TOTAL HYDROFGEN SUPPLY RATE OF 200 TO 20.000 S.D.F. OF HYDROGEN PER BARREL OF FEEDSTOCK, REMOVING AMMONIA FROM THE EFFLUENT FROM SAID REACTION ZONE, AND RECOVERING HYDROFINED AND HYDROCRACKED PRODUCTS FROM SAID REACTION ZONE, SAID CATALYST COMPRISING: (A) A GEL MATRIX COMPRISING: (A) AT LEAST 15 WEIGHT PERCENT SILICA, (B) ALUMINA, IN AN AMOUNT PROVIDING AN ALUMINATO-SILICA WEIGHT RATIO OF 15/85 TO 80/20, (C) NICKEL OR COBALT, OR THE COMBINATION THEREOF, IN THE FORM OF METAL, OXIDE, SULFIDE OR ANY COMBINATION THEREOF, IN AN AMOUNT OF 1 TO 10 WEIGHT PERCENT, BASED ON SAID MATRIX, CALCULATED AS METAL, (D) MOLYBDENUM OR TUNGSTEN, OR THE COMBINATION THEREOF, IN THE FORM OF METAL, OXIDE, SULFIDE OR ANY COMBINATION THEREOF, IN AN AMOUNT OF 5 TO 25 WEIGHT PERCENT, BASED ON SAID MATRIX, CALCULATED AS METAL; (B) A CRYSTALLINE ZEOLITIC MOLECULAR SIEVE: (A) CONTAINING FROM 0.1 TO 2.0 WEIGHT PERCENT PALLADIUM, CALCULATED AS METAL, (B) CONTAINING LESS THAN 5 WEIGHT PERCENT SODIUM, (C) BEING IN PARTICULATE FORM AND BEING DISPERSED THROUGHOUT SAID MATRIX BY COGELATION OF SAID MATRIX AROUND SAID SIEVE; SAID CATALYST COMPOSITE BEING FURTHER CHARACTERIZED BY IN AVERAGE PORE DIAMETER BELOW 100 ANGTROMS AND A SURFACE AREA ABOVE 200 SQUARE METERS PER GRAM.
