Product Description Product Description Product DescriptionProducts Introduction of 4A Type Molecular SieveMolecular 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.

A properly regenerated molecular sieve can give moisture dew points below -100°C.The outlet concentrations on a pressure swing process will depend on the gas present, and on the conditions of the process.AttentionTo avoid damp and pre-adsorption of organic before running, or must to be reactivated.Packaging & Shipping Certifications
