4A Molecular Sieve Absorbent
Desheng 4A Molecular Sieve
Adsorbs H2O, CO2, SO2, H2S, C2H4, C2H6, C3H6, ethanol. Will not adsorb C3H8 and higher hydrocarbons. Good for drying.
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). XINTAO 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.
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.
