Beta zeolite is one king of high SiO2ï¼?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 Beta zeolite is0.56Ã?0.76nm, Beta zeolite only has duct without cages, so it is able to exchange all the cations. Beta 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, Beta 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, Beta zeolite is able to decrease the solidifying point of diesel oil. Beta 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 Beta 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 Beta zeolite will play important role to solve this question .Fuethetmore, for some dismutation reaction such as dimethyl benzene , C9 and transalkylation reaction , Beta 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. Beta zeolite is the catalyst with high activity for dehydration and deammonia reaction.
Our factory is able to produce 400 tons of Beta zeolite which SiO2ï¼?AL2O3 ratio is from 20 to pure silicon per year. Our product, Beta zeolite, possesses excellent competitive position of quality and price in the internal and international market.
