Molecular Sieve 3A

Molecular Sieve 3A is an alkali metal aluminosilicate; Molecular sieve 3A is the potassium form of the type A crystal structure. Molecular sieve 3A adsorbs molecules with effective diameters small than 3 angstrom (0.3nm) such as water and exclude molecular

Product Description

Molecular Sieve 3A is made from zeolite powder 3A (>70%) and binder. Zeolite powder 3A is a potassium-based type A zeolite, which is generated by replacing part of sodium cation in 4 angstrom sieves. Molecular sieve 3A is usually used for dehydration. Since it only adsorbs molecule with diameter less than 3 angstroms. Molecular sieve 3A is a perfect adsorbent if you only want to remove water from gas mixture in most condition. Molecular Sieve 3A have the shape of beads and pallets.

Application:

1. Zeolite molecular sieve 3A is used for drying of unsaturated hydrocarbons (e.g. ethylene, propylene, butadiene)

2. Zeolite molecular sieve 3A is used in deep desiccation of cracked petroleum gases, such as ethylene, propylene, butadiene, acetylene and natural gas, and of polar liquid, such as ethanol, LPG and solvent

3. Zeolite molecular sieve 3A is used in drying of natural gas, if COS minimization is essential, or a minimum co-adsorption of hydrocarbons is required

4. Zeolite molecular sieve 3A is used in drying of highly polar compounds, such as methanol and ethanol

5. Zeolite molecular sieve 3A is used in drying of refrigerants (e.g. R22, R134a etc)

6. Zeolite molecular sieve 3A is used in dehydration of benzene, toluene, xylene and other solvents 

7. Zeolite molecular sieve 3A is used in static, (non-regenerative) dehydration of insulating glass units
