AI Technical Summary
Technical Problem
Existing hydrocracking catalysts have insufficient catalytic capacity and low catalytic activity. The microporous molecular sieves have a single and small pore size, which limits the diffusion and conversion rate of reactants.
Method used
By employing Y-zeolite, β-zeolite, alumina, and optionally amorphous silica-alumina composite support, a porous structure is formed by controlling the ratio of micropores, mesopores, and macropores, thereby enhancing the synergistic effect of the catalyst's pore structure.
Benefits of technology
It significantly improved the catalytic activity and conversion rate of the catalyst, and optimized the mass transfer and conversion process of the reactants.

Abstract
This invention relates to the field of catalysts, and discloses a catalyst support and its preparation method, as well as a catalyst and its application. The catalyst support contains Y-zeolite, β-zeolite, alumina, and optionally amorphous silica-alumina. The Y-zeolite comprises micropores with a pore size less than 2 nm, mesopores with a pore size of 2-50 nm, and macropores with a pore size greater than 50 nm. Taking the total volume of micropores, mesopores, and macropores as 100%, the micropore volume accounts for less than 40%, the mesopore volume accounts for 20-80%, and the macropore volume accounts for less than 40%.
