A PROCESS FOR HYDROCRACKING A HYDROCARBON CHARGE CONTAINING AT LEAST 1 WEIGHT PERCETN PYRENES TO LOWER BOILING PRODUCTS, WHICH COMPRISES: DIVIDING SAID HYDROCARBON CHARGE INTO A FIRST FRACTIN CONTAINING LESS THAN 1 WEIGHT PERCENT PYRENES AND A SECOND FRACTION CONTAINING MORE THAN 1 WEIGHT PERCENT PYRENES; HYDROCRACKING SAID FIRST FRACTION BY CONTACTING SAID FIRST FRACTION UNDER HYDROCRACKING REACTION CONDITIONS WHICH INCLUDE A HYDROGEN PRESSURE BELOW 1500 P.S.I.G. WITH A DUAL FUNCTION HYDROCRACKING CATALYST WHICH EMPLOYS AT LEAST ONE NOBLE METAL OF THE PONENT; HYDROCRACKING SAID SECOND RACTION BY CONTACTING SAID SECOND FRACTION UNDER HYDROCRACKING REACTION CONDITIONS WHICH INCLUDE A PRESSURE OF AT LEAST ABOUT 2000 P.S.I.G. WITH A DUAL FUNCTION CATALYST WHICH EMPLOYS AT LEAST ONE NOBLE METAL OF THE PLATINUMAND PALLADIUM SERIES AS HYDROGENATION COMPONENT, TO PRODUCE LOWER BOILING PRODUCTS, WHEREBY SAID CHARGE IS CONVERTED TO HIGH YIELDS OF DESIRABLE PRODUCTS WHILE THE AGING OF SAID CATALYSTS IS MINIMIZED.
