β-zeolite is one king of high SiO2／Al2O3 ratio zeolites with three-dimensional twelve-membered rings ,composed of double six-membered rings with two four-membered rings .The diameter of the main duct of β-zeolite is0.56×0.76nm, 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 above14%,and also has a high thermostability.
Because of the feature of duty, β-zeolite has high selectivity of chain hydtocarbon 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 .Fuethetmore, 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 propence to isopropyl-benzene and ethylbenzene . β-zeolite is the catalyst with high activity for dehydration and deammonia reaction .
Our factory is able to produce 1000 tons of β-zeolite which SiO2／Al2O3 ratio is from 20 to pure silicon per year. Our product, β-zeolite, possesses excellent competitive position of quality and price in the internal and international market.
