<p>The invention pertains to a hydroprocessing catalyst suitable for the conversion of heavy hydrocarbon oils, which comprises 7 to 20 weight% of Group VI metal, Calculated as trioxide, and 0.5 to 6 weight % of Group VIII metal, calculated as oxide, on a carrier comprising alumina, the catalyst having a surface area of 100 to 180 m2/g; a total pore volume of 0.55 ml/g or more, a %PV (>200 Ad) of at least 50%, a %PV(>1000 A d) of at least 5%, a %PV(100 to 1200 A d) of at least 85%, a %PV(>4,000 A d) of 0 to 2%, and a %PV( 10000 >00 A d) of 0 to 1%. The catalyst of the present invention shows improved metals and asphaltene removal, combined with appropriate sulfur, nitrogen, and Conradson carbon removal. Additionally, the catalyst shows a decrease in sediment formation and an improved conversion in ebullating bed operations. In fixed bed operation, the catalyst produces product with an improved storage stability. The invention also pertains to a process for hydroprocessing heavy hydrocarbon feeds with the catalyst according to the invention in fixed bed or ebullating bed operation. ></p> |
