Molecular Sieves 4A
Molecular Sieve 4A is an alkali aluminosilicate; it is the sodium form of the Type A crystal structure. Molecular sieve 4A has an effective pore opening of about 4 angstroms ( 0.4nm) . It 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.
