Molecular sieves are sorted by the size of the opening in their crystal structure, measured in ångströms.
- 3A — adsorbs water but excludes most other molecules. Use it for ethanol dehydration and drying cracked gas.
- 4A — the general-purpose desiccant for natural gas, refrigerants and insulated glass.
- 5A — separates normal from branched paraffins and is used in hydrogen PSA.
- 13X — the largest pore; removes water and CO₂ from air and is used in oxygen concentrators.
