Description

technical field [0001] The invention relates to the field of molecular sieve treatment, in particular to ceramic membrane cleaning equipment and a method for synthesizing Beta molecular sieves based on an organic template-free method. Background technique [0002] Beta molecular sieve has the characteristics of high thermal stability and good hydrophobicity, and is an ideal adsorbent for adsorbing VOCs. For the application of Beta molecular sieve, the most critical issue is the preparation of Beta molecular sieve. Hydrothermal synthesis is a classic synthesis method of Beta molecular sieves, which requires expensive organic templates to participate in the synthesis process to play a role in structure orientation. [0003] Generally speaking, the yield of molecular sieve synthesized by hydrothermal method is generally 50-80%, so the crystallization mother liquor after molecular sieve synthesis will contain a large amount of unreacted raw material components and molecular siev...
