Heavy hydrocarbons are hydrotreated to increase content of components boiling below 1000°F. by contact with Group VIII non-noble metal oxide and Group VI-B metal oxide on alumina having a Total Surface Area of 150-240 m2/g, a Total Pore Volume, (TPV) of 0.7-0.98, and a Pore Diameter Distribution whe
Heavy hydrocarbons are hydrotreated to increase content of components boiling below 1000°F. by contact with Group VIII non-noble metal oxide and Group VI-B metal oxide on alumina having a Total Surface Area of 150-240 m2/g, a Total Pore Volume, (TPV) of 0.7-0.98, and a Pore Diameter Distribution whereby ≤20% of the TPV is present as primary micropores of diameter ≤100 Å, at least about 34% of TPV is present as secondary micropores of diameter of about 100 Å-200 Å, and about 26%-46% of the TPV is present as mesopores of diameter >200 Å.

A process for hydrotreating a charge hydrocarbon feed containing components boiling above 1000°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 prese
A process for hydrotreating a charge hydrocarbon feed containing components boiling above 1000°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 m2/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 Å, 34-69% of the Total Pore Volume is present as secondary micropores of diameters of about 100 Å-200 Å, about 26-35% of the Total Pore Volume is present as mesopores of diameter 200 Å, about 22-32% of the Total Pore Volume is in pores having diameters 250 Å, and macropores of diameters 1000 Åare 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°F., sediment, sulfur, metals, carbon residue, asphaltenes, and nitrogen; and recovering said hydrotreated product containing decreased content of components boiling above 1000°F., sediment, sulfur, metals, carbon residue, asphaltenes and nitrogen.
