Hydroconversion process employing catalyst with specified pore size distribution

A process of hydrotreating a charge hydrocarbon containing sulfur and metals which comprises

• contacting said charge hydrocarbon feed with hydrogen and a catalyst at isothermal hydrotreating conditions, said catalyst consisting essentially of 3-3.5% NiO or CoO, 14.5-16.5% MoO.sub.3, and 1.5-3w % of P.sub.2 O.sub.5 all supported on a porous alumina support, said catalyst having a Total Surface Area of 240-280 m.sup.2 /g, a Total Pore Volume of 0.65-0.75 cc/g, and a Pore Diameter Distribution whereby 63-78% of the Total Pore Volume is present as micropores of diameter 55-115.ANG. and 15-17% of the Total Pore Volume is present as macropores of diameter greater than 250.ANG., thereby forming hydrotreated product containing decreased content of components boiling above 1000.degree. F., and sulfur, metals and carbon residue;
• and
• recovering said hydrotreated product containing decreased content of components boiling above 1000.degree. F., and sulfur, metals, and carbon residue.

A process for hydroconversion of a charge hydrocarbon feed of boiling point greater than 1000.degree. F. to form product having a boiling point less than 1000.degree. F. which comprises

• contacting said charge hydrocarbon feed with hydrogen and a catalyst at isothermal hydrotreating conditions, said catalyst consisting essentially of 3-6w % of a Group VIII metal oxide and 14.5-24w % of molybdenum oxide, said catalyst having a Total Surface Area of 240-310 m.sup.2 /g, a Total Pore Volume of 0.5-0.75 cc/g, and a Pore Diameter Distribution whereby 63-78% of the Total Pore Volume is present as micropores of diameter 55-115.ANG. and 11-18% of the Total Pore Volume is present as macropores of diameter greater than 250.ANG., thereby forming hydrotreated product containing increased content of product having a boiling point less than 1000.degree. F.;
• and
• recovering said forming hydrotreated product containing increased content of product having a boiling point less than 1000.degree. F.

A process for hydroconversion of a charge hydrocarbon feed of boiling point greater than 1000.degree. F. to form product having a boiling point less than 1000.degree. F. which comprises

• contacting said charge hydrocarbon feed with hydrogen and a catalyst at isothermal hydrotreating conditions, said catalyst consisting essentially of a 3-3.5w % of NiO or CoO, 14.5-16.5w %, of MoO.sub.3, and 1.5-3w % of P.sub.2 O.sub.5, said catalyst having a Total Surface Area of 240-280 m.sup.2 /g, a Total Pore Volume of 0.65-0.75 cc/g and a Pore Diameter Distribution whereby 1-6% of the Total Pore Volume is present as micropores of diameter less than 55.ANG., 63-78% of the Total Pore Volume is present as micropores of diameter 55-115.ANG., 15-17% of the Total Pore Volume is present as macropores of diameter greater than 250.ANG., and 10-14% of the Total Pore Volume is present in macropores of diameter 500-10,000.ANG., thereby forming hydrotreated product containing increased content of product having a boiling point less than 1000.degree. F.;
• and
• recovering said hydrotreated product containing increased content of product having a boiling point less than 1000.degree. F.
