Beta- 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 beta - zeolite is0.*6 0.*6nm, 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 above*4%, 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
toluene, dimethyl benzene , C9 and transalkylation reaction
, beta - zeolite has excellent stability and selectivity.
In fine chemical industry, beta - 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 **0 tons of beta - zeolite which
SiO2/AL2O3 ratio is from *0 to pure silicon per year. Our
product, beta - zeolite, possesses excellent competitive
position of quality and price in the internal and international
market.
