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.
