Patent ID: 8883669

Claim:
A hydrocracking catalyst, comprising a carrier, an effective quantity of at least one VIII Group metal component(s), an effective quantity of at least one VIB Group metal component(s), and an organic additive, wherein the organic additive is one or more selected from the group consisting of oxygen-containing compounds and nitrogen-containing organic compounds, and a molar ratio of the organic additive to the VIII Group metal component(s) is 0.01-10, wherein the alumina carrier comprises an acidic silica-alumina, alumina (A), and alumina (B), wherein a weight percentage of alumina (A) is 51-90 wt % and a weight percentage of alumina (B) is 10-49 wt % based on a total weight of alumina (A) and alumina (B), and wherein alumina (A) has a pore volume of pores having a diameter in the range of 60-600 angstrom being more than 70% of the total pore volume of alumina (A), and alumina (B) has a pore volume of pores having a diameter of less than 80 angstrom being more than 95% of the total pore volume of alumina (B).
