13XAPG Molecular Sieve is Sodium aluminosilicate, It could absorb the molecular which diameter is not more than 9 angstroms. It can remove impurities too larger to fit into a type A crystal and is commonly used to separate N2 from O2. 13X APG Molecular Sieve is the sodium form of the type X crystal and has a much larger pore opening than the type A crystals. It has the highest capacity of common adsorbents and excellent mass transfer rates.
13X-APG molecular sieve is an alkali metal aluminosilicate with a sodium X-type crystal structure. Its pore size is about 10Å (angstroms), so it can adsorb molecules with a critical diameter of less than 10Å. It is widely used due to its efficient co-adsorption ability (capable of removing water and carbon dioxide simultaneously) and excellent carbon dioxide selective adsorption in certain situations.
Chemical formula: Na2O*Al2O3*(2.8±0.2)SiO2*(6-7)H2O
Silicon-aluminum ratio: SiO2/Al2O3≈2.6-3.0
