Title:

BETA MOLECULAR SIEVE, PREPARATION METHOD THEREFOR AND HYDROGENATION CATALYST CONTAINING SAME

Document Type and Number:

WIPO Patent Application WO/2015/078256

Kind Code:

A1

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 SiO2/Al2O3 is 30-150, the non-framework aluminium accounts for not more than 2% of the total aluminium, 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 vapour, and then with ammonium fluosilicate. The beta molecular sieve of the present invention has the features of a uniform skeleton structure of silicon and aluminium, 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.
