BETA-MOLECULAR SIEVE, METHOD FOR ITS PRODUCTION AND HYDROGENATION CATALYST CONTAINING THIS SIEVE Russian patent published in 2018 - IPC C01B39/48 B01J29/70 B01J29/78 

FIELD: biotechnology.

SUBSTANCE: beta-molecular sieve, a process for its production, and a hydrogenation catalyst containing this sieve are provided. Beta-molecular sieve is characterized by the following properties: molar ratio of SiO₂/Al₂O₃ is 30-150, the amount of non-frame aluminium is not more than 2% of the total aluminium amount, and the number of silicon atoms, coordinated in the Si(0Al) structure is not less than 95% of the number of silicon atoms in frame structure. The production method comprises contacting of the initial zeolite powder β with moving water vapour of normal pressure at a temperature of 500-650 °C for 5-10 hours and subsequent contacting with ammonium fluorosilicate.

EFFECT: beta-molecular sieve of this invention is characterized by a homogeneous frame aluminosilicate structure, suitable acidity and appropriate pore structure, is suitable as an acid catalyst component of hydroforming and hydrocracking catalyst for diesel fuel.
