Beta沸石是具有三维十二员孔道结构的大孔高硅沸石。在烃类裂解 、异构化、烷基化，石油的脱蜡等方面，均有着广泛的应用。另外，公司生产的B 沸石在汽车尾气NOx的SCR 催化、汽车冷启动污染物吸附，VOC 吸附等领域有广泛的应用，该材料大批量供应庄信万丰公司。

Zeolite-Beta is high silica whose structure possesses three-dimensional 12-membered ring pores with an interconnected channel system. Zeolite-Beta is a good catalyst in hydrocracking of the long-chain alkanes, isomerization and elementary cracking and hydrodewaxing. Besides, Zeolite-Beta we produced has a good properties of SCR activity of NOx, large absorbed capacity for pollutant in cold star process. Beta Zeolite also can be used in VOC adsorption. This product was provided to Johnson matthey in large scale.
