Heavy oils may be hydrotreated in the presence of a porous alumina support bearing metals of Group VIII, excluding cobalt, and VI-B and optionally phosphorus, the catalyst having a Total Surface Area of 240-320 m2/g, a Total Pore Volume of 0.65-0.9 cc/g, and a Pore Diameter Distribution whereby 50-6
Heavy oils may be hydrotreated in the presence of a porous alumina support bearing metals of Group VIII, excluding cobalt, and VI-B and optionally phosphorus, the catalyst having a Total Surface Area of 240-320 m2/g, a Total Pore Volume of 0.65-0.9 cc/g, and a Pore Diameter Distribution whereby 50-62.8% of the Total Pore Volume is present as micropores of diameter 55-115 Åand 20-30.5% of the Total Pore Volume is present as macropores of diameter greater than 250 Å. The heavy oils and hydrogen are contacted with the catalyst such that the catalyst is maintained at isothermal conditions and is exposed to a uniform quality of feed. The process is particularly effective in achieving desired levels of hydroconversion of feedstock components having a boiling point greater than 1000°F. to products having a boiling point less than 1000°F.

A process for hydrotreating a charge hydrocarbon feed containing components boiling above 1000°F., and sulfur, and metals, and carbon residue which comprises contacting said charge hydrocarbon feed with hydrogen at isothermal hydrotreating conditions in the presence of, as catalyst, a porous alumina
A process for hydrotreating a charge hydrocarbon feed containing components boiling above 1000°F., and sulfur, and metals, and carbon residue 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-cobalt Group VIII metal oxide, 14.5-24 wt % of a Group VI-B metal oxide, and 0-4 wt % of a phosphorus oxide, said catalyst having a Total Surface Area of 240-320 m2/g, a Total Pore Volume of 0.65-0.9 cc/g, and a Pore Diameter Distribution whereby 50-62.8% of the focal Volume Pore is present as micropores of diameter 55-115 Å, 27.5-37% of the Total Pore Volume is present in large pores of a diameter greater than 160 Å, and 20-30.5% of the Total Pore Volume is present as macropores of diameter greater than 250 Å, thereby forming hydrotreated product containing decreased content of components boiling above 1000°F. and sulfur, metals, and carbon residue; and recovering said hydrotreated product containing decreased content of components boiling above 1000°F., sulfur, metals, and carbon residue.
