Abstract

The invention discloses a preparation method of a hydrocracking catalyst. The preparation method comprises the following steps: (1) pulping raw material powder of a hydrocracking catalyst carrier component, performing high-temperature and high-speed stirring treatment while pulping, filtering, and drying a filter cake, wherein the hydrocracking catalyst carrier component comprises a molecular sieve, and further comprises at least one of aluminum oxide, amorphous aluminium silicon, amorphous magnesium silicon and clay; (2) shaping the dried material, drying, roasting for activating, and preparing into a catalyst carrier; (3) loading a hydrogenating active component by an impregnation method to obtain the hydrocracking catalyst. Compared with the prior art, the preparation method of the hydrocracking catalyst has the advantage as follows: by the preparation method, a synergistic effect between different components can be further promoted, so that the using performance of the catalyst is improved.

Description

Technical field [0001] The invention relates to a hydrocracking catalyst and a preparation method thereof, in particular to a hydrocracking catalyst for producing high-quality chemical raw materials and a preparation method thereof. technical background [0002] In the 21st century, the consumption growth of petrochemical products has surpassed that of petroleum products, and large-scale ethylene and large-scale aromatics plants will become important directions for the development of petrochemicals. The refinery produces naphtha in accordance with the principle of "ene is suitable for olefin, aromatic for aromatic, and oil for oil". Both ethylene cracking raw materials and catalytic reforming raw materials must be provided to produce high-octane gasoline. Blending components and aromatic hydrocarbon feedstock. Hydrocracking technology has become the core of the oil-chemical-fiber combination of refineries due to its advantages of strong feedstock oil adaptability, high productio...
