13X APG Molecular Sieve

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 will adsorb molecules with a kinetic diameter of less than 9 angstroms (0.9nm) and exclude those larger. It has the highest capacity of common adsorbents and excellent mass transfer rates. It can remove impurities too larger to fit into a type A crystal and is commonly used to separate N2 from O2. Chemical Molecular Formula: Na2O·Al2O3·2.45SiO2·6.0H2O.   (SiO2:Al2O3≈2.6-3.0). Typical Application: Removal of H2O from the air for air cryo-separation application.
