ANYUAN Molecular Sieve type 4A is an alkali alumina 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). It will adsorb most molecules with a kinetic diameter of less than 4 angstroms and exclude those larger.Such adsorbable molecules include simple gas molecules such as oxygen, nitrogen, carbon dioxygen and straight chain hydrocarbons. Branched chain hydrocarbons and aromatics are excluded.
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 | ||||
| 5A-DW | 0.45-0,50 | 21-22 | 0.3-0.6 | Aviation kerosense, dewaxing and alkance sparation |
