Hydrocracking process employing a catalyst containing a group viii metal component

Claim 1

AN IMPROVED HYDROCRACKING PROCESS COMPRISING HYDROCRACKING A HYDROCARBON FEED TO PRODUCTS BOILING BELOW THE INITIAL BOILING POINT OF SAID FEED BY CONTACTING SAID FEED, IN THE PRESENCE OF HYDROGEN AND UNDER HYDROCRACKING CONDITIONS, WITH A CATALYST COMPRISING AT LEAST ONE GROUP VIII METAL-CONTAINING HYDROGENATING-DEHYDROGENATING COMPONENT INCORPORATED WITHIN AN ACIDIC SOLID XEROGEL COMPRISING SILICA AND AT LEAST ONE OTHER METALLIC OXIDE SELECTED FROM THE GROUP CONSISTING OF OXIDES OF METALS OF GROUPS II, III AND IV OF THE PERIODIC TABLE, SAID CATALYST BEING PREPARED BY ADDING AT LEAST ONE ALKYLENE OXIDE, CONTAINING FROM 2 TO 3 CARBON ATOMS PER MOLECULE, TO A MIXTURE COMPRISING A SILICA SOL, AT LEAST ONE GROUP VIII METAL HALIDE AND AT LEAST ONE OTHER METAL HALIDE, THE METAL OF SAID HALIDE BEING THE SAME METAL AS THAT PRESENT IN SAID ACIDIC SOLIC XEROGEL, ALL OF SAID HALIDES BEING SOLUBLE IN SAID SILICA SOL, ALLOWING SAID MIXTURE TO SET INTO A HYDROCOGEL, AND DEHYDRATING SAID HYDROCOGEL TO PRODUCE SAID CATALYST.
