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.

Hydrocracking catalyst, a process for producing the same, and the use of the same

The present invention relates to a catalytic conversion process for producing more diesel and propylene, comprising contacting the feedstock oil with a catalyst having a relatively homogeneous activity in a reactor, wherein the reaction temperature, weight hourly space velocity and weight ratio of the catalyst/feedstock oil are sufficient to obtain a reaction product containing from 12 to 60% by weight of a fluid catalytic cracking gas oil relative to the weight of the feedstock oil; the fluid catalytic cracking gas oil is fed into the fluid catalytic cracking gas oil treatment device for further processing. Catalytic cracking, hydrogenation, solvent extraction, hydrocracking and process for producing more diesel are organically combined together, and hydrocarbons such as alkanes, alkyl side chains in the feedstock for catalysis are selectively cracked and isomerized.

Catalytic conversion process for producing more diesel and propylene

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&#x2dc;60 wt %, the content of said alumina is 10&#x2dc;80 wt %, and the content of said organic additive is 0.1&#x2dc;40 wt % based on the weight of said catalyst; the content of said VIII Group metal component is 1&#x2dc;15 wt % and the content of said VIB Group metal component is 5&#x2dc;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.
