Heavy hydrocarbons are hydrotreated to increase content of components boiling below 1000°F. by contact with Group VIII non-noble metal oxide and Group VIB metal oxide on alumina having a Total Surface Area of 175-220 m2/g, a Total Pore Volume (TPV) of 0.6-0.8, and a Pore Diameter Distribution whereb
Heavy hydrocarbons are hydrotreated to increase content of components boiling below 1000°F. by contact with Group VIII non-noble metal oxide and Group VIB metal oxide on alumina having a Total Surface Area of 175-220 m2/g, a Total Pore Volume (TPV) of 0.6-0.8, and a Pore Diameter Distribution whereby ≤33% of the TPV is present as primary micropores of diameter ≤100 Å, at least about 41% of TPV is present as secondary micropores of diameter of about 100 Å-200 Å, and about 16%-26% of the TPV is present as mesopores of diameter ≥200 Å. Phosphorus containing compounds are avoided during catalyst preparation.

A process for hydrotreating a charge hydrocarbon feed containing components boiling above 1000°F., toluene insolubles formers, sulfur, metals, asphaltenes, carbon residue, and nitrogen which comprises contacting said charge hydrocarbon feed with hydrogen at isothermal hydrotreating conditions in the
A process for hydrotreating a charge hydrocarbon feed containing components boiling above 1000°F., toluene insolubles 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 VIB metal oxide, 0-2 wt % of silica, and 0-2 wt % of a phosphorus oxide, said catalyst having a Total Surface Area of 175-220 m2/g, a Total Pore Volume of 0.6-0.8 cc/g, and a Pore Diameter Distribution wherein less than about 33% of the Total Pore Volume is present as primary micropores of diameter less than about 100 Å, at least about 41% of the Total Pore Volume is present as secondary micropores of diameter of about 100Å-200 Åand about 16-26% of the Total Pore Volume is present as mesopores of diameter ≥200 Å, thereby forming hydrotreated product containing decreased contents of components boiling above 1000°F., toluene insolubles, sulfur, metals, carbon residue, asphaltenes and nitrogen; and recovering said hydrotreated product containing decreased content of components boiling above 1000°F., toluene insolubles, sulfur, metals, carbon residue, asphaltenes and nitrogen.
