| Model | Pore diameter (Ångström) | Bulk density (g/ml) | Adsorbed water (% w/w) | Attrition or abrasion, W (% w/w) | Usage[14] |
|---|---|---|---|---|---|
| 3Å | 3 | 0.60–0.68 | 19–20 | 0.3–0.6 | Desiccation of petroleum cracking gas and alkenes, selective adsorption of H2O in insulated glass (IG) and polyurethane |
| 4Å | 4 | 0.60–0.65 | 20–21 | 0.3–0.6 | Adsorption of water in sodium aluminosilicate which is FDA approved (see below) used as molecular sieve in medical containers to keep contents dry and as food additive having E-number E-554 (anti-caking agent); Preferred for static dehydration in closed liquid or gas systems, e.g., in packaging of drugs, electric components and perishable chemicals; water scavenging in printing and plastics systems and drying saturated hydrocarbon streams. Adsorbed species include SO2, CO2, H2S, C2H4, C2H6, and C3H6. Generally considered a universal drying agent in polar and nonpolar media;[12] separation of natural gas and alkenes, adsorption of water in non-nitrogen sensitive polyurethane |
| 5Å-DW | 5 | 0.45–0.50 | 21–22 | 0.3–0.6 | Degreasing and pour point depression of aviation kerosene and diesel, and alkenes separation |
| 5Å small oxygen-enriched | 5 | 0.4–0.8 | ≥23 | Specially designed for medical or healthy oxygen generator[citation needed] | |
| 5Å | 5 | 0.60–0.65 | 20–21 | 0.3–0.5 | Desiccation and purification of air; dehydration and desulfurization of natural gas and liquid petroleum gas; oxygen and hydrogen production by pressure swing adsorption process |
| 10X | 8 | 0.50–0.60 | 23–24 | 0.3–0.6 | High-efficient sorption, used in desiccation, decarburization, desulfurization of gas and liquids and separation of aromatic hydrocarbon |
| 13X | 10 | 0.55–0.65 | 23–24 | 0.3–0.5 | Desiccation, desulfurization and purification of petroleum gas and natural gas |
| 13X-AS | 10 | 0.55–0.65 | 23–24 | 0.3–0.5 | Decarburization and desiccation in the air separation industry, separation of nitrogen from oxygen in oxygen concentrators |
