High Purity Natural 4a Molecular Sieve Desiccant For Ammonia Refrigerator Compressor

Pure Natural 4a Molecular Sieve Desiccant For Ammonia Refrigerator Compressor


Overview


4a molecular sieve is a synthetic zeolite of A-type crystal structure in potassium-sodium form with a pore opening of 4 angstroms (0.4 nm). Adsorb water, methanol, ethanol, hydrogen sulfide, sulfur dioxide, carbon dioxide, ethylene, propylene, NH3, H2S, CO, methyl chloride, methyl bromide, methyl acetylene, ethane. Does not adsorb any molecular diameter greater than 4 angstroms (including propane). The more powerful selective adsorption capacity than any other molecular sieve. It is mainly applied in the drying gas, liquid. Widely used in drying oilfield associated gas and natural gas. Also widely used for the dehydration of ethanol.


Molecular FormulaNa2O·Al2O3·2SiO2·9/2H2O
SiO2/ Al2O3≈ 2
Normal Pore Opening4 Angstroms (Å)
Regeneration temp. (°C)200-315
AdvantagesHigh Stability; High Strength; Large Water Absorption; Low Attrition; Deep Dehydration
