Zeolite Desiccant Molecular Sieve for Ethanol Distillation
Zeolite Desiccant Molecular Sieve 1.For drying and purifying 2.Applied to cracked gas,ethylene, propylene, butylene, butadien
The pore size of 3A molecular sieve is 3A . It does not absorb any molecular larger than 3A. It is an alkali metal alumino-silicate, the potassium form of the type A crystal structure. 3 Angstrom, is obtained when part of the sodium ions of the 4 Angstrom sieve are replaced by potassium ions. Will absorb, in sequence of adsorption rate, helium, neon, nitrogen and water.
Properties and application of molecular sieve:
| Type | Bulk density Yp(g/ml) | Water absorption A(%) | Wear Ability W(%) | Appllcation |
| 3A | 0.60-0.68 | 19-20 | 0.3-0.6 | Drying for pyrolysis gas and alkene |
| 4A | 0.60-0.65 | 20-21 | 0.3-0.6 | Drying for nature gas and alkene separation |
| 5A | 0.60-0.65 | 20-21 | 0.3-0.5 | Dehydration, desulfurization and purification of air, nature gas |
| and petroleum in oxygen-making and hydrogen-making by PSA processes | ||||
