Hydrocracking hydrocarbons with a platinum group metal deposited on an active cracking catalyst base

Claim 1

A CATALYTIC PROCESS FOR HYDROCRACKING A RELATIVELY HIGH BOILING DISTILLATE HYDROCARBON FRACTION, HAVING AN INITIAL BOILING POINT OF AT LEAST ABOUT 400*F., A 50 PERCENT POINT OF AT LEAST ABOUT 500*F., AND AN END POINT OF AT LEAST ABOUT 600*F., AND BOILING SUBSTANTIALLY CONTINUOUSLY BETWEEN SAID INITIAL BOILING POINT AND SAID END POINT, INTO HYDROCARBON PRODUCTS SELECTED FROM THE GROUP CONSISTING OF SUBSTANTIALLY FUEL OIL, SUBSTANTIALLY GASOLINE, AND A MIXTURE OF SUBSTANTIALLY GASOLINE AND SUBSTANTIALLY FUEL OIL, WHEREIN THERE IS SUBSTANTIALLY NO COKE FORMATION AND THE PRODUCTION OF C1, C2 AND C3 GASEOUS HYDROCARBONS IS LESS THAN ABOUT 10 PERCENT BY WEIGHT OF SAID RELATIVELY HIGH BOILING PETROLEUM HYDROCARBON FRACTION, WHICH COMPRISES CONTACTING SAID RELATIVELY HIGH BOILING PETROLEUM HYDROCARBON FRACTION WITH A CATALYST THAT INCLUDES BETWEEN 0.05 PERCENT, BY WEIGHT, AND ABOUT 20 PERCENT, BY WEIGHT OF A METAL SELECTED FROM THE GROUP OF METALS HAVING ATOMIC NUMBERS OF 44 TO 46, INCLUSIVE, AND 76 TO 78, INCLUSIVE, DEPOSITED UPON A SYNTHETIC COMPOSITE THAT HAS AN ACTIVITY INDEX GREATHER THAN 25 AND WHICH IS SELECTED FROM THE GROUP CONSISTING OF SILICA-ALUMINA, SILICA-ZIRCONIA, SILICA-ALUMINA-ZIRCONIA, SILICA-ALUMINA-THORIA, ALUMINABORIA, SILICA-MAGNESIA, SILICA-ALUMINA-MAGNESIA AND SILICAALUMINA-FLUORINE, AT A TEMPERATURE WITHIN THE RANGE ABOUT 400*F. TO ABOUT 825*F., AT A HYDROGEN PRESSURE, AND WITH A NET CONSUMPTION OF HYDROGEN, WITHIN THE RANGE ABOUT 100 POUNDS PER SQUARE INCH GAUGE TO ABOUT 2500 POUNDS PER SQUARE INCH GAUGE, AT A LIQUID HOURLY SPACE VELOCITY WITHIN THE RANGE ABOUT 0.1 TO ABOUT 10. AND AT RATIOS OF HYDROGEN TO HYDROCARBON WITHIN THE RANGE ABOUT 2 TO ABOUT 80, AND CORRELATING SAID TEMPERATURE WITH SAID LIQUID HOURLY SPACE VELOCITY TO PRODUCE LESS THAN ABOUT 10 PERCENT C1, C2 AND C3 GASEOUS HYDROCARBONS AND TO PRODUCE HYDROCARBON PRODUCTS SELECTED FROM THE GROUP CONSISTING OF SUBSTANTIALLY FUEL OIL, SUBSTANTIALLY GASOLINE, AND A MIXTURE OF SUBSTANTIALLY GASOLIE AND SUBSTANTIALLY FUEL OIL.
