Provided is a Na&#x2014;Y molecular sieve and a method for preparing the Na&#x2014;Y molecular sieve, an H&#x2014;Y molecular sieve and a method for preparing the H&#x2014;Y molecular sieve, a hydrocracking catalyst, and a hydrocracking method. The average grain diameter of the Na&#x2014;Y molecular sieve is 2-5 &#x3bc;m, and the sum of pore volumes of pores in 1-10 nm diameter accounts for 70-90% of the total pore volume of the Na&#x2014;Y molecular sieve. The H&#x2014;Y molecular sieve obtained from the large-grain Na&#x2014;Y molecular sieve can be used as an acidic component in the hydrocracking catalyst. When the hydrocracking catalyst containing the H&#x2014;Y molecular sieve is applied in the hydrocracking reaction of heavy oils that contain macromolecules, it can provide better cracking activity and product selectivity in the hydrocracking reaction.

Disclosed are a beta molecular sieve, a preparation method therefor, and a hydrogenation catalyst containing same. The properties of the beta molecular sieve are as follows: the molar ratio of SiO/AlOis 30-150, the non-framework aluminum accounts for not more than 2% of the total aluminum, and the silicon atoms coordinated in a Si(OAl) structure account for not less than 95% of the silicon atoms in the framework structure. The preparation method comprises: contacting the raw material powder of the beta molecular sieve with normal pressure and dynamic water vapor, and then with ammonium fluosilicate. The beta molecular sieve of the present invention has the features of a uniform skeleton structure of silicon and aluminum, an appropriate acidity, and a reasonable pore structure, and is suitable as an acidic component of a hydro-upgrading catalyst and a hydro-cracking catalyst for diesel oil.
