Molecular Sieves
1)Beta-type zeolites possess a unique three-dimensional intersecting pore structure formed by twelve-membered rings. They are composed of a mixture of two closely related polymorphs, which are constructed from tetrahedral structural units arranged in layers with the same center of symmetry. Both structures are built from the same tertiary structural units (TBU), which are arranged in layers and then linked in left-handed and right-handed forms. This connection results in the twisting of the pores along the C-direction.
Beta zeolite exhibits excellent catalytic performance in petroleum refining and petrochemical processes such as catalytic cracking, hydrocracking, hydroisomerization, hydrodeoxygenation, alkylation of aromatics, olefin hydration, and olefin etherification.
2)The ZSM-5 molecular sieve catalyst is widely used in the petrochemical processing industry. It serves as an additive in the fluid catalytic cracking process to enhance the production of propylene and liquefied petroleum gas, as well as to improve the octane number of gasoline. Additionally, it can be employed in the production of ethylbenzene, para-xylene, phenol, pyridine, and other compounds
3)The Y-type zeolite is the most widely used among all zeolites. Post-treated modified Y-type zeolite serves as the primary active component in fluid catalytic cracking catalysts. It is also employed in hydrogenation cracking, isomerization, and alkylation catalysts. Unmodified NaY zeolite, which has not undergone exchange modification, functions as an efficient desiccant.
