Detail
4A Molecular Sieve 3-5mm available to supply !
Introduction
Molecualr sieve 4A Adsorbentis an alkali alumina 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.
Typical Chemical Formula
0.4K2O 0.6Na2O Al2O32SiO2 4.5H2O
SiO2 : Al2O3 ≈2
Technical Parameter
Typical Application
1) Drying and removing of CO2 from natural gas, LPG, air, inert and athmospheric gases, etc
2)Removal of hydrocarbons, ammonia and methanol from gas streams (ammonia syn gas treating)
3) Special types are used in the air break units of buses, trucks and locomotives
4) Packed in small bags, it may be used simply as a packaging desiccant
