Abstract
The present invention provides a hydrocracking catalyst comprising a moulded composite support of a zeolite molecular sieve with alumina, at least one of VIII Group metal components, at least one of VIB Group metal components and an organic additive; said organic additive is one or more compounds selected from the group consisting of oxygen-containing or nitrogen-containing organic compounds; the content of said zeolite molecular sieve is 3˜60 wt %, the content of said alumina is 10˜80 wt %, and the content of said organic additive is 0.1˜40 wt % based on the weight of said catalyst; the content of said VIII Group metal component is 1˜15 wt % and the content of said VIB Group metal component is 5˜40 wt % as calculated on oxide and based on the weight of said catalyst. The present invention relates also to a preparation method of said hydrocracking catalyst and use of the catalyst in the hydrocracking process of hydrocarbon oil. In comparison with the method in existing arts, the hydrocracking catalyst provided according to the present invention has the aromatic-hydrogenation conversion activity increased obviously.
