Abstract
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.
