A PROCESS FOR HYDROCRACKING HYDROCARBONS WHICH COMPRISES CONTACTING THE HYDROCARBON IN A HYDROCRACKING ZONE WITH A CATALYST PREPARED BY CONTACTING SILICA, HAVING HYDROGEN ATOMS IN SURFACE HYDROXYL GROUPS CAPABLE OF IONIZING AND EXCHANGING, WITH AN IONIC SOLUTION OF AN ALUMINUM SALT AT A TEMPERATURE IN THE RANGE 0-100* C. SUCH THAT FROM 0.1 TO 3% IONS OF THE ALUMINIUM, EXPRESSED AS PERCENT BY WEIGHT OF THE SILICA, IS INCORPORATED ONTO THE SURFACE OF THE SILICA, AND FROM 0.1 TO 50% WEIGHT, BASED ON THE FINAL CATALYST, OF A CATALYTIC COMPONENT SELECTED FROM THE GROUP CONSISTING OF A PLATINUM AND PALLADIUM ALSO BEING INCORORATED WITH THE SILICA, AND CONTACTING BEING CARRIED OUT AT A TEMPERATURE IN THE RANGE 450-950*F., A PRESSURE OF 230 TO 3000 P.S.I.G., A SPACE VELOCITY OF 0.2-5.0 V./V./HR., AND A HYDROGEN RATE OF 1000 TO 20,000 S.C.F./B.
