Title:
水素化処理用触媒並びに水素化処理方法
Document Type and Number:
Japanese Patent JP4638610
Kind Code:
B2
Abstract:
The invention pertains to a hydroprocessing catalyst suitable for the conversion of heavy hydrocarbon oils, which comprises 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 a surface area of about 100-180 m2/g, a total pore volume of about 0.55 ml/g or more, a % PV(>200 Å d) of at least about 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%. 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.
