China Beta Molecular Sieves - Top Suppliers & Factory for Catalytic Performance in Petrochemical Processes
The Beta molecular sieve has a unique structure of three dimensional twelve ring cross pore. It is composed of a mixture of two closely related polycrystalline bodies, which are composed of tetrahedral units arranged in layers symmetrical to the same center. Both structures are composed of tertiary units (TBU) paired by the same center, which are arranged in layers and then connected in the form of left and right hands. This connection causes the channel to twist along the C direction.
Beta molecular sieves show excellent catalytic performance in catalytic cracking, hydrocracking, hydroisomerization, hydrodewaxing, aromatic alkylation, olefin hydration, olefin etherification and other petroleum refining and petrochemical processes.
What is the unique structure of a Beta molecular sieve?
The Beta molecular sieve features a unique three-dimensional twelve-ring intersecting pore structure, composed of intergrown polymorphs of tetrahedral units arranged in symmetrical layers.
What are the primary applications of Beta molecular sieves?
They are widely used in petroleum refining and petrochemical processes, including catalytic cracking, hydrocracking, hydroisomerization, hydrodewaxing, and aromatic alkylation.
How does the channel structure behave in Zeolite Beta?
Due to the connection of tertiary building units (TBU) in left- and right-handed configurations within the layers, the channel system twists along the C-crystallographic direction.
Can Beta molecular sieves be used for olefin reactions?
Yes, they show excellent catalytic activity in processes such as olefin hydration and olefin etherification.
What types of Beta molecular sieves are available?
Common specifications include Beta-25, Beta-30, Beta-50, and Beta-B, tailored to meet different catalytic and selectivity requirements.
