Beta zeolite catalyst (β Zeolite) or Beta molecular sieve is a synthetic aluminosilicate zeolite with a BEA framework structure. It possesses a unique three-dimensional interconnected pore system, the pore openings of the straight channels are approximately 0.66 nm × 0.67 nm, while the curved channels have pore dimensions of about 0.56 nm × 0.56 nm.
The framework of Beta zeolite consists of SiO4 and AlO4 tetrahedra linked through shared oxygen atoms, forming a highly stable crystalline network. The presence of framework aluminum generates negative charges that can be balanced by various cations, making Beta zeolite available in different forms such as H-Beta, NH4-Beta, Na-Beta, Rare Earth Beta, and metal-modified Beta molecular sieves.
Beta zeolite catalyst has abundant Brønsted acid sites and excellent acid-catalytic activity, especially for H-Beta. In petrochemical industry, Beta zeolite serves as an active component in FCC, hydrocracking, catalytic dewaxing, and hydroisomerization catalysts. In fine chemical and petrochemical synthesis processes, Beta zeolite exhibits excellent catalytic activity for alkylation, transalkylation, acylation, and aromatization reactions.
In addition to catalyst, Beta zeolite is also an important adsorbent and separation material due to its uniform pore structure, high specific surface area, and adjustable surface properties. It is capable of selectively adsorbing and separating various hydrocarbons, organic compounds, and industrial gases, making it useful in purification and separation processes.
