Molecular Sieve type 4A is an alkali alumino silicate; it is the sodium forms of the type A crystal structure.4A molecular sieve has an effective pore opening of about 4 angstroms (0.4nm). 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 dioxide and straight chain hydrocarbons. Branched chain hydrocarbons and aromatics are excluded.
Molecular Sieve 4A is generally used to remove moisture or to refine material and can be applied to the liquefied and gaseous materials on the whole. Main adsorbing target is water and it can adsorb all the material whose molecular diameter is less than 4A.The main uses are as follows.
