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.

We can produce beta zeolite according customers demand.

Our zeoite and catalyst factory are in follow.

The fixed-bed catalyst production project covers an area of about 5,000 square meters and a building area of 2,000 square meters. It is fully equipped with public works and has more than 40 sets of catalyst production equipment. It has a complete fixed-bed catalyst production system, and the production units that can be carried out mainly include: pretreatment of catalyst raw powder, impregnation, molding, drying/roasting, screening and environmental protection treatment, etc., which can meet the production of various fixed-bed catalysts.
