13X APG adsorbent is the sodium form of the type X molecular sieve and an alkali metal aluminosilicate. 13X APG adsorbent will adsorb molecules with critical diameters up to 10 angstroms.
Chemical Formula: Na2O•Al2O3• (2.8±0.2) SiO2• (6-7) H2O
Si/Al ratio: SiO2/Al2O3≈2.6-3.0
Pore diameter: About 10A
Use: Used for general air-drying, purifying raw gas and remove H2O, CO2 and hydrocarbons for medium and large size air-separation equipment.
