1.deep drying natural gas alkane,2.used for dehydratlon of varlous gasss - details see: https://www.machineto.com/molecular-sieve-4a-dg-10000001

4dgA Molecular Sieve Adsorbent is a clay-bound sodium form of Type A molecular sieve. 4A molecular sieve will adsorb molecules with critical diameters up to 4 angstroms. It adsorbs water and ethanol, but not larger molecules like propane.

APPLICATIONS

• Deep drying of gases and liquids, such as natural gas alkane, air, carbon dioxide etc.
• Static drying for electronic component and hygroscopic substance
• Dehydration of coating and polyester etc.

Chemical Formula

Type 3A can be adsorbed on Type 4A. Na₁₂[(AlO₂)₁₂(SiO₂)₁₂].XH₂O
