What is a Molecular Sieve for CO₂ Removal?
Molecular sieves are crystalline aluminosilicates with precise pore sizes used to adsorb gases and vapors. When used for carbon dioxide removal, they selectively trap CO₂ molecules based on molecular diameter and polarity making them ideal for gas separation, dehydration, and air purification.
3A Molecular Sieve: Potassium based, 3 angstrom pores
4A Molecular Sieve: Sodium based, 4 angstrom pores
Both types belong to Type A zeolites, with 4A having greater affinity for carbon dioxide due to its slightly larger pore structure and higher surface interaction with CO₂ molecules.
Technical Comparison: 3A vs 4A for CO₂ Removal
Property | 3A Molecular Sieve | 4A Molecular Sieve |
|---|---|---|
| Pore Size | ~3 Å | ~4 Å |
| Chemical Base | Potassium Ion | Sodium Ion |
| CO₂ Adsorption Capacity | Moderate | High |
| Preferred Application | Moisture removal, air drying | CO₂ + moisture removal |
| Particle Forms | Beads, pellets | Beads, pellets |
| Typical Use | PSA systems, dryers | Natural gas, LPG, cracked gas |
