08 Selection guide
Which adsorbent does your process need?
Start from your process; the key figure shows why each grade is the usual choice.
| Process | Recommended grades | Key figure |
|---|---|---|
| Natural gas dehydration | 4A main layer, activated alumina guard, ceramic ball support | 4A static H₂O ≥ 22.5 % |
| Air pre-purification (ASU) | 13X APG, CaX, activated alumina | 13X APG CO₂ ≥ 8.0 ml/g at 2.5 mmHg |
| PSA / VPSA oxygen | Li-LSX, 13X | Li-LSX N₂/O₂ selectivity ≥ 6.2 |
| PSA hydrogen | 5A, activated alumina | 5 Å pore takes up CO, CO₂ and n-paraffins |
| Compressed air drying | Activated alumina, 4A, 13X | Pressure dew point to −70 °C with 4A |
| Biogas upgrading & CO₂ capture | CO₂ adsorbent, methane enrichment sieve | Static CO₂ adsorption ≥ 18 % |
| Ethanol & olefin drying | 3A | 3 Å pore excludes ethanol and ethylene |
| Refrigerant drying | Refrigerant molecular sieve | Static H₂O ≥ 21.5 %, refrigerant excluded |
| VOC abatement | Hydrophobic zeolite | ≈ 0.55 nm pores, non-flammable |
| Drinking-water defluoridation | Fluoride removal alumina | Fluoride below the WHO 1.5 mg/L guideline |
| CO recovery from syngas | Cu(I) CO adsorbent | Separates CO from N₂ of near-identical size |
| Cryogenic vacuum insulation | Silver zeolite hydrogen getter | Silver content ≥ 40 % |
