Preparation of β molecular sieve

Preparation of zeolite β

In the chemical field, our beta molecular sieve is widely used, in life, beta zeolite structure makes us curious, it features with little toxicity, it basically is to solve the problem of filtering difficult, in the study, preparation of beta zeolite a patent technology, below we know about the preparation of beta zeolite was simple:

The invention provides a method for preparing β molecular sieve, in which kaolin, bentonite and other natural minerals are used as raw materials to provide all or part of the aluminum source, and organic ammonium template is added to carry out the crystallization reaction under hydrothermal conditions, and a crystallization product containing β molecular sieve is obtained. The modified β molecular sieves obtained from the crystallization products can be prepared by different post-treatment methods, which can be used as the active component or carrier of the catalyst. The β molecular sieve prepared by the method has higher thermal and hydrothermal stability; The β molecular sieve prepared by the method solves the problem of filtration difficulty in the preparation and post-treatment of β molecular sieve, and can improve the production efficiency. The method extends the range of raw materials for the synthesis of β molecular sieve, finds new uses for more natural minerals, and further reduces the cost of preparing β molecular sieve.
