molecular sieve type 4a,
4 angstrom molecular sieves
Zeolite Molecular Sieve 4A Dryer For Methanol Drying
Molecular Sieve 4A is an alkali alumino 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). RP type 4A molecular sieve will adsorb most molecules with a kinetic diameter of fewer than 4 angstroms and exclude those larger. Such adsorbable molecules include simple gas molecules such as oxygen, nitrogen, carbon dioxide and straight chain hydrocarbons. Branched chain hydrocarbons and aromatics are excluded.
1. Oxygen Adsorption
2. Nitrogen Adsorption
3. Carbon Dioxide Adsorption
4. Packaging of Pharmaceuticals
5. Packaging of Perishable Chemicals
6. Packaging of Electronics
7. Water Scavenger in Paint Systems
8. Water Scavenger in Plastic Systems
9. Commercial Drying of Saturated Hydrocarbons
10. Drying and removing of CO2 from natural gas, LPG, air, inert and atmospheric gases, etc.
11. Removal of hydrocarbons, ammonia and methanol from gas streams (ammonia syngas treating)
12. Special types are used in the air break units of buses, trucks and locomotives.
13. Packed in small bags, it may be used simply as a packaging desiccant.
