Single-stage hydrocracking process with a nitrogen containing feed stock

Claim 1

A PROCESS FOR THE SINGLE-STAGE DENITRIFICATIONB AND HYDROCRACKING OF HYDROCARBON FEEDSTOCKS CONTAINING MORE THAN ABOUT 550 P.P.M. OF NITROGEN AND BOILING IN THE RANGE FROM ABOUT 400* TO ABOUT 1400*F. TO PRODUCE AT LEAST ONE PRODUCT FRACTION BOILING BELOW THE INITIAL BOILING POINT OF SAID FEEDSTOCK, WHICH COMPRISES CONTACTING SAID FEEDSTOCK, ALONG WITH FROM 500 TO 2000 STANDARD CUBIC FEET PER BARREL OF ADDED HYDROGEN, IN A HYDROCARACKING ZONE AT A TEMPERATURE OF FROM ABOUT 650* TO ABOUT 950*F., A PRESSURE OF FROM ABOUT 800 TO ABOUT 3000 P.S.I.G. AND AN L.H.S.V. OF FROM ABOUT 0.1 TO ABOUT 10.0 WITH A NITIROGENINSENSITIVE CATALYST COMPRISING AT LEAST ONE GROUP VI METAL SULFIDE WITHIN A SILICA-ALUMINA GEL, SAID CATALYST MANUFACTURED BY THE STEPS COMPRISING: (A) FORMING A MIXTURE COMPRISING A SILICA SOL, AT LEAST ONE SOLUBLE ALUMINUM COMPOUND, AND AT LEAST ONE SOLUBLE COMPOUND OF A GROUP VI METAL; (B) REACTING SAID MIXTURE FORMED IN STEP (A) WITH A QUANTITY OF AN EPOXY COMPOUND SUFFICIENT TO CONVERT SAID MIXTURE INTO A HYDROGEL; (C) DEHYDRATING SAID HYDROGEL TO PRODUCE A GEL COMPRISING SILICA, ALUMINA AND AT LEAST ONE GROUP VI METAL OXIDE; AND (D) CONVERTING SAID GROUP VI METAL TO ITS CORRESPONDING SULFIDE BY CONTACT WITH A SULFUR-CONTAINING FLUID.
