Zeolite beta
β molecular sieves have three mutually intersecting 12-ring channels, it is only 12 yuan a three-dimensional pore structure of zeolite ring.
β zeolite having high hydrocracking, hydroisomerization catalytic activity and adsorption capacity of linear paraffins, and good resistance to sulfur and nitrogen poisoning. It can be used in the petrochemical industry of benzene with propylene olefin system cumene, cumene metathesis diisopropylbenzene, toluene Isopropylation, aromatics alkylation, transalkylation diisopropylbenzene, propylene ether, methanol aryl structured, propylene oxide and acetic ether of phenol methylation, methylation of aniline, toluene transalkylation preparation of cumene and toluene disproportionation and transalkylation reaction with a catalyst such. β-type USY zeolite used in conjunction with the increase of the octane number of gasoline. In the fine chemical industry, β zeolite has excellent activity and selectivity in the dehydration deamination.

Zeolite beta is used in isomerization of waxes, and Friedel Crafts reactions (alkylation and acylation)Zeolite β, hydrogen is used as a molecular sieve, filter, adsorbent, catalyst, drying agent, cation exchanger, dispersing agent and detergent builder. It serves as an acid catalyst and utilized as an alternative to the known methods for protection of alcohols as tetrahydropyranyl ethers and the deprotection of tetrahydropyranyl ethers. It is also used in the stereoselective Meerwein-Ponndorf-Verley reduction of ketones. Further, it is used as an efficient and recyclable catalyst for the tetrahydropyranylation of alcohols and phenols
We can produce beta zeolite according customers demand.
