Abstract
The present invention relates to a hydrocracking catalyst comprising an acidic silica-alumina, an optional alumina, 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 an oxygen-containing or nitrogen-containing organic compound, and the molar ratio of the organic additive to the VIII Group metal component(s) is 0.01-10. The present invention relates further to a process for producing the hydrocracking catalyst and use of the catalyst in a process for hydrocracking hydrocarbon oils. The hydrocracking catalyst provided according to the present invention shows a higher activity for aromatic hydrosaturating and ring-opening reaction, as compared with the prior art hydrocracking catalyst.
