Beta-type molecular sieve has a unique three-dimensional twelve-membered ring cross pore structure. It is composed of a mixture of two closely related polymorphs. The two polycrystals are composed of tetrahedral structural units symmetrically arranged in layers with the same center. Both structures are composed of three-level structural units (TBU) paired with the same center. These TBUs are arranged in layers and then connected in the form of left and right hands. This connection results in a torsion of the channel in the C direction.
Beta molecular sieves show excellent catalytic performance in petroleum refining and petrochemical processes such as catalytic cracking, hydrocracking, hydroisomerization, hydrodewaxing, aromatic alkylation, olefin hydration, and olefin etherification.
