Molecular sieve is a kind of synthetic molecular screening of hydrated silicon aluminate (zeolite) or natural zeolite, it has a lot of aperture on structure of concreted complete neat rows of cavity, different aperture of molecular sieve to separate different molecular size and shape. Molecular sieves with different pore sizes were obtained according to the molecular ratios of SiO2 and Al2O3. The models are: 3A(potassium A type), 4A(sodium A type), 5A(calcium A type), 13X(sodium X type), etc. It has high adsorption capacity, high selectivity and high temperature resistance. It is widely used in organic and petrochemical industries and is also an excellent adsorbent for gas dewatering. More and more attention has been paid to waste gas purification.

Product Performance
a. Adsorption performance The adsorption of zeolite molecular sieve is a physical change process. Gravity causes of adsorption is mainly molecules in the solid surface to produce a "surface force", when the fluid flows through some of the fluid molecules due to the collision and irregular exercise to the surface of adsorbent, the surface molecules together, reduce the number of molecules in fluid, achieve the purpose of separation, remove.
b. Ion exchange performance In general, ion exchange refers to the exchange of compensated cation outside the zeolite molecular sieve framework. Compensation outside of zeolite molecular sieve skeleton ion is usually protons and alkali metal or alkaline earth metal, they are easily in metal salt aqueous solution by ion exchange into various valence metal ionic type zeolite molecular sieve.
c. Catalytic performance Most zeolites have strong acid centers on the surface of zeolite molecular sieve. These properties make it an excellent catalyst.
