Heavy crude conversion

Claim 1

IN A PROCESS FOR UPGRADING THE 1050*F. + MATERIALS OF A METALS CONTAINING HEAVY CRUDE OR RESIDUA BY CONVERSION OF THE 1050*F.+ MATERIALS TO PRODUCE 1050*F.- MATERIALS, THE IMPROVED COMBINATION COMPRISING CONTACTING SAID HEAVY CRUDE OR RESIDUA IN AN INITIAL REACTION ZONE, IN THE PRESENCE OF ADDED HYDROGEN, WITH A CATALYST CHARACTERIZED AS COMPRISING A COMPOSITE OF FROM ABOUT 5 TO ABOUT 30 PERCENT OF A GROUP VIB METAL, OR COMPOUND THEREOF, FROM ABOUT 1 TO ABOUT 12 PERCENT OF A GROUP VII METAL, OR COMPOUND THEREOF, OR ADMIXTURE OF SAID GROUP VIB AND GROUP VIII METALS, OR COMPOUNDS THEREOF, AND A POROUS INORGANIC OXIDE SUPPORT, SAID CATALYST INCLUDING A COMBINATION OF PROPERTIES COMPRISING AT LEAST ABOUT 50 PERCENT OF ITS TOTAL PORE VOLUME OF ABSOLUTE PORE DIAMETER TERS RANGING FROM ABOUT 200A TO ABOUT 300A, AND LESS THAN ABOUT 20 PERCENT OF ITS TOTAL PORE VOLUME ARE OF ABOSLUTE PORE DIAMETERS RANGING FROM 0 TO ABOUT 100A, A SURFACE AREA RANGING AT LEAST ABOUT 200 M2/G TO ABOUT 600 M2/G AND A PORE VOLUME RANGING FROM ABOUT 0.8CC/G TO ABOUT 3.0 CC/G, AT SEVERITY SUFFICIENT TO CONVERT AT LEAST ABOUT 30 PERCENT OF THE 1050*F + MATERIAL TO 1050*F.MATERIAL, WHILE REMOVING AT LEAST ABOUT 75 PERCENT OF THE HEAVY METALS FROM THE FEED, AND CONTACTING PRODUCT OF SAID INITIAL REACTION ZONE IN A SUBSEQUENT REACTION ZONE, IN THE PRESENCE OF ADDED HYDROGEN, WITH A CATALYST WHICH CONTAINS A METAL HYDROGENATION COMPONENT, AND ABOVE ABOUT 30 PERCENT ALUMINUM PHOSPHATE, BASED ON THE WEIGHT OF THE CATALYST (DRY BASIS) EXCLUSIVE OF THE HYDROGENATION COMPONENT, SAID CATALYST HAVING AT LAST ABOUT 90 PERCENT OF ITS TOTAL PORE VOLUME OF ABSOLUTE DIAMETER WITHIN THE RANGE OF ABOUT 15A TO ABOUT 100A, A SURFACE AREA RANGING FROM ABOUT 200M2/G TO ABOUT 600M2/G AND A PORE VOLUME RANGING FROM ABOUT 0.25 TO ABOUT 0.75 CC/G, AND THE REACTION IS CONDUCTED AT SEVERITIES SUFFICIENT TO HYDROGENITROGENATE THE 1050*F.FRACTION OF THE PRODUCT OF SAID INITIAL REACTION ZONE FED THERETO TO THE EXTENT OF AT LEAST ABOUT 30 PERCENT, BASED ON THE WEIGHT OF TOTAL NITROGEN CONTAINED IN THE REACTION MIXTURE, ON THE NITROGEN BEING ELIMINATED AS AMMONIA.
