Patent ID: 7169294

Claim:
A hydroprocessing catalyst useful for the conversion of heavy hydrocarbon oils comprising about 7–20 wt. % of Group VI metal, calculated as trioxide, and about 0.5–6 wt. % of Group VIII metal, calculated as oxide, on a carrier comprising alumina, the catalyst having the following physical properties: a surface area of about 100–180 m 2 /g, a total pore volume of about 0.55 ml/g or more, a %PV(>200 Å d) of at least 50%, a %PV(>1,000 Å d) of at least about 5%, a %PV(100–1,200 Å d) of at least about 85%, a %PV(>4,000 Å d) of about 0–2%, and a %PV(>10,000 Å d) of about 0–1%.
