Beta-B
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. -

ZSM-5B
ZSM-5 molecular sieve is a high-silicon zeolite, its Si/Al ratio can be as high as 1000 or more, and this kind of molecular sieve also shows the characteristics of hydrophobic. Their structure is characterized by the crystal silicaluminate composed of 10-element pores. Its basic structural unit is composed of eight five-membered rings, no cage cavity, only channels. ZSM-5 has two sets of intersecting channels, one straight through and the other perpendicular to each other. The channel is elliptical and its window diameter is 0.55-0.60nm. Due to the similar reaction space and the shape of the inlet and outlet, this kind of molecular sieve has a shape selection effect on the reactants and products, coupled with the homogeneity of its structure and hydrothermal stability, making it a good selective catalyst raw material.
ZSM-5 molecular sieve catalyst is widely used in petrochemical processing industry. It can be used as an auxiliary agent in the process of fluid catalytic cracking, which can increase propylene and liquefied gas production and improve the octane number of gasoline. In addition, it can be used for the production of ethylbenzene, p-xylene, phenol, pyridine, etc. -
