Patent ID: 8334231

Claim:
A hydrocracking catalyst, comprising a moulded composite support of a zeolite molecular sieve with alumina, at least one of Group VIII metal components, at least one of Group VIB metal components and an organic additive, wherein said organic additive is one or more compounds selected from the group consisting of oxygen-containing and nitrogen-containing organic compounds, and the content of said zeolite molecular sieve is 3 to 60 wt %, the content of said alumina is 10 to 80 wt % and the content of said organic additive is 0.1 to 40 wt %, based on the weight of said catalyst; and the content of said Group VIII metal component is 1 to 15 wt % and the content of said Group VIB metal component is 5 to 40 wt %, as calculated on oxide and based on the weight of said catalyst, and wherein said zeolite molecular sieve has a B-acid/L-acid ratio of more than 0.9, and has at least one characteristic peak corresponding to a silicon-hydroxy group appearing in the range of 3760˜3685 cm −1 as measured by infrared spectroscopy.
