Product Description

3.0-3.5mm 4A Molecular Sieve Desiccant With High Crush Strength


Usage of 4A Molecular Sieve Desiccant:

- Drying and removing of CO2 from natural gas, LPG, air, inert and atmospheric gases, etc.

- Removal of hydrocarbons, ammonia, and methanol from gas streams (ammonia syngas treating).

- Special types are used in the air break units of buses.

- Packed in small bags, it may be used simply as a packaging desiccant.


Introduction of 4A Molecular Sieve Desiccant:

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 Formula Na2O·Al2O3·2SiO2·9/2H2O
SiO2/ Al2O3 ≈ 2
Normal Pore Opening 4 Angstroms (Å)
Regeneration temp. (°C) 200-315
Advantages High Stability; High Strength; Large Water Absorption; Low Attrition; Deep Dehydration
