Claims
- 1. A process for hydrotreating a charge hydrocarbon feed containing components boiling above 1000.degree. F., and sediment-formers, sulfur, metals asphaltenes, carbon residue, and nitrogen which comprises:
- contacting said charge hydrocarbon feed with hydrogen at isothermal hydrotreating conditions in the presence of, as catalyst, a porous alumina support bearing 2.5-6 wt % of a non-noble Group VIII metal oxide, 13-24 wt % of a Group VI-B metal oxide, and 0-2 wt % of a phosphorus oxide, said catalyst having a Total Surface Area of 165-210 m.sup.2 /g, a Total Pore Volume of 0.75-0.95 cc/g, and a Pore Diameter Distribution whereby 5-18% of the Total Pore Volume is present as primary micropores of diameters less than about 100 .ANG., 34-69% of the Total Pore Volume is present as secondary micropores of diameters of about 100 .ANG.-200 .ANG., about 26-35% of the Total Pore Volume is present as mesopores of diameter <200 .ANG., about 22-32% of the Total Pore Volume is in pores having diameters <250 .ANG., and macropores of diameters <1000 .ANG. are present in an amount of about 14-22% of the total pore volume, thereby forming hydrotreated product containing decreased contents of components boiling above 1000.degree. F., sediment, sulfur, metals, carbon residue, asphaltenes, and nitrogen; and
- recovering said hydrotreated product containing decreased content of components boiling above 1000.degree. F., sediment, sulfur, metals, carbon residue, asphaltenes and nitrogen.
- 2. A process for hydrotreating a charge hydrocarbon feed as claimed in claim 1 wherein the catalyst further comprises silica (SiO.sub.2) in an amount less than about 2.5 wt %.
- 3. A process for hydrotreating a charge hydrocarbon feed as claimed in claim 1 wherein the Pore Volume of pores of diameter less than about 100 .ANG. is 0.04 cc/g to 0.15 cc/g.
- 4. A process for hydrotreating a charge hydrocarbon feed as claimed in claim 1 wherein secondary micropores of diameter of about 100-200 .ANG. are present in an amount of about 50% to 69% of Total Pore Volume.
- 5. A process for hydrotreating a charge hydrocarbon feed as claimed in claim 1 wherein secondary micropores of diameter of about 100-200 .ANG. are present in an amount of about 0.40 cc/g to 0.66 cc/g.
- 6. A process for hydrotreating a charge hydrocarbon feed as claimed in claim 1 wherein mesopores of diameter of <200 .ANG. are present in an amount of 19.5-33.2 cc/g.
- 7. A process for hydrotreating a charge hydrocarbon feed as claimed in claim 1 wherein macropores of diameter .ltoreq.1000 .ANG. are present in an amount of about 0.11-0.20 cc/g.
- 8. A process for hydrotreating a charge hydrocarbon feed containing components boiling above 1000.degree. F., and sediment-formers, sulfur, metals, asphaltenes, carbon residue, and nitrogen which comprises
- contacting said charge hydrocarbon feed with hydrogen at isothermal hydrotreating conditions in the presence of, as catalyst, a porous alumina support bearing 2.5-6 wt % of a non-noble Group VIII metal oxide 13-24 wt % of a Group VI-B metal oxide, and less than about 0.2 wt % of a phosphorus oxide, said catalyst having a Total Surface Area of 165-210 m.sup.2 /g, a Total Pore Volume of 0.75-0.95 cc/g, and a Pore Diameter Distribution whereby less than about 15% of the Total Pore Volume is present as primary micropores of diameters less than about 100 .ANG., at least about 50% of the Total Pore Volume is present as secondary micropores of diameters of about 100 .ANG.-200 .ANG., about 26-35% of the Total Pore Volume is present as mesopores of diameters <200 .ANG., 22-32% of the Total Pore Volume is in pores with diameters <250 .ANG. and about 14-22% of the Total Pore Volume is present as macropores of diameters <1000 .ANG., thereby forming hydrotreated product containing decreased contents of components boiling above 1000.degree. F., sediment, sulfur, metals, carbon residue, asphaltenes, and nitrogen; and
- recovering said hydrotreated product containing decreased content of components boiling above 1000.degree. F., sediment, sulfur, metals, carbon residue, asphaltenes, and nitrogen.
