Molecular Sieve 3A
Molecular Sieve 3A is one kind of alkali metal alumino-silicate. Sometimes, it is also called 3A zeolite molecular sieve.
The aperture of this molecular sieve is 3A. Therefore,It does not adsorb the objects whose molecular diameters are larger than 3Å.
3Amolecular sieve's formula is 2/3K2O•1/3Na2O•Al2O3• 2 SiO2 • 9/2 H2O. 3A molecular sieve desiccant is the necessary desiccant in petroleum, chemical industry.
A 4 to 8-mesh sieve is normally used in gasphase applications, while the 8 to 12-mesh type is common in liquidphase applications.
he powder forms of the 3A, 4A, 5A and 13X sieves are suitable for specialized applications.

4A Molecular Sieve
Molecular Sieve type 4A is an alkali alumino silicate; it is the sodium form of the Type A crystal structure. 4A molecular sieve has an effective pore opening of about 4 angstroms (0.4nm). Type 4A molecular sieve will adsorb most molecules with a kinetic diameter of less than 4 angstroms and exclude those larger. Such adsorbable molecules include simple gas molecules such as oxygen, nitrogen, carbon dioxyde and straight chain hydrocarbons. Branched chain hydrocarbons and aromatics are excluded.

5A Molecular Sieve
5A molecular sieve pore size for 5A, can adsorption is less than the diameter of any molecule, is mainly used in heterogeneous hydrocarbon separation, pressure swing adsorption, adsorption separation and water and carbon dioxide, based on the industrial application characteristics of 5A molecular sieve, we in the production of 5A molecular sieve choose high adsorption, adsorption speed, especially suitable for the pressure swing adsorption, can adapt to all kinds of size of oxygen, hydrogen, carbon dioxide and other gases pressure swing adsorption device, is the high-quality goods in the industry pressure swing adsorption (PSA
