Zeolite Molecular Sieve Principle

Zeolite molecular sieves possess a crystalline structure and characteristics, with a solid framework on the surface and internal pores that can adsorb molecules. These pores are interconnected by channels through which molecules pass. Thanks to the crystalline nature of the pores, the molecular sieve exhibits an exceptionally uniform pore size distribution.

Molecular sieves selectively adsorb molecules based on the size of the pores within their crystal structures—meaning they attract molecules of a certain size while repelling larger ones—hence the aptly named "molecular sieve." The ability of molecular sieves to adsorb or reject molecules is also influenced by the molecules' electrical properties. Synthetic zeolites, in particular, exhibit unique selective adsorption capabilities tailored to both the size and polarity of molecules, making them ideal for drying or purifying gases and liquids. This property forms the very basis for the separation processes molecular sieves are capable of performing.

Synthetic zeolites can meet the chemical industry's broad demand for adsorption and selective products, and in the chemical industry, synthetic zeolite molecular sieves are also applied to the adsorption and separation of chemical molecules.
