13X molecular sieve

13XMS

The 13X molecular sieve is the sodium form of zeolite X and has a much larger pore opening than the type A crystals, with an effective pore diameter of 10 angstroms. It also has the highest theoretical capacity of the common adsorbents and excellent mass transfer rates.

Product Details

Features

  • 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 angstrom(0.9nm) and exclude those larger.
  • It have the highest capacity of the common adsorbents and very good 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).

Applications

  1. Removal of H2O from air for air cryo-separation application.
  2. Application of 13X Type Molecular Sieve
  3. Removal of CO2 and moisture from air (air pre-purification) and other gases.Separation of enriched oxygen from air.
  4. Removal of mercaptans and hydrogen sulphide from natural gas.
  5. Removal of mercaptans and hydrpogen sulphide from hydrocarbon liquid streams (LPG, butane, propane etc.Catalyst protection,
  6. Removal of oxygenates from hydrocarbons (olefin streams).
  7. Production of bulk oxygen in PSA units.
  8. Production of medical oxygen in small scale oxygen concentrators.
