Sell Molecular Sieve for Dehydration

详情

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 dioxide and straight chain hydrocarbons. Branched chain hydrocarbons and aromatics are excluded. Application - Drying and removing of CO2 from natural gas, LPG, air, inert and athmospheric gases, etc. - Removal of hydrocarbons, ammonia and methanol from gas streams (ammonia syn gas treating) - Special types are used in the air break units of buses, trucks and locomotives. - Packed in small bags, it may be used simply as a packaging desiccant.
