Description

β-zeolite is one kind of highSi*2/Al2O3 ratio zeolites with three-dimensional twelve-membered rings, composed of double six-membered rings with two four-membered rings and four five-membered rings. The diameter of the main duct of β-zeolite is 0.*6×0.*6nm. β-zeolite only has duct without cages, so it is able to exchange all the cations. β-zeolite has relatively large absorptive capacity of cyclohexane and n-hexane, each above *4%, and also has a high thermostability.
Because of the feature of duct, β-zeolite has high selectivity of chain hydrocarbon in cracking reaction. Used into petroleum hydrocarbon cracking industry to obtain of high carbon low freezing-point cracking product, β-zeolite is able to decrease the solidifying point of diesel oil. β-zeolite is a new hydro cracking catalyst producing diesel oil with low solidifying point, so it has a good industrial application prospect in oil refining industry.

In petrochemical industry, at present, the decreasing olefin catalyst can both reduce olefin and octane ratio in gasoline. Adding modified β-zeolite into FCC catalyst is able to decrease the content of olefin in catalysts cracking reaction, and increase octane ratio simultaneously. So the FCC catalyst with modified β-zeolite will play important role to solve this question. Furthetmore, for some dismutation reaction such as toluene, dimethyl benzene, C9 and transalkylation reaction, β-zeolite has excellent stability and selectivity.

In fine chemical industry, β-zeolite has already been used both in the alkylation of propene to isopropyl-benzene and ethane to ethylbenzene. β-zeolite is the catalyst with high activity and selectivity for dehydration and deammonia reaction.

Our factory is able to produce **0 tons of β-zeolite which SiO2/Al2O3 ratio is from *0 to pure silicon per year. Our product, β-zeolite, possesses excellent competitive position of quality and price in the internal and international market
