Description

technical field

[0001] The invention relates to a method for synthesizing Beta molecular sieves. Background technique

[0002] Beta molecular sieve is the only zeolite with three-dimensional twelve-membered ring straight channel system. Its unique pore structure and acidity make Beta molecular sieve have high catalytic activity for hydrocracking, hydroisomerization and adsorption capacity for linear alkanes. And has good resistance to sulfur and nitrogen poisoning. It can be used in the petrochemical industry to produce cumene by alkylation of benzene and propylene, disproportionation of cumene to dicumene, isopropylation of toluene, alkylation of aromatics, transalkylation of dicumene, etherification of propylene, methanol aromatics Preparation of catalysts for structuralization, etherification of propylene oxide and ethanol, methylation of phenol, methylation of aniline, transalkylation of cumene and toluene, and disproportionation and transalkylation of toluene. The com...
