13X Molecular Sieves

13X molecular sieve, also called Natrium X molecular sieve, Zeolite 13X, is a kind of alkali metal silicon aluminate, its skeleton structure composed of silica and alumina tetrahedral FAU, main crystal holes are twelvering structures. To the X type molecular sieve,if silicon aluminum ratio is not the same, crystal structures are different. 13X molecular sieve silicon aluminum ratio≈2.6-3.0 (SiO2/Al2O3≈2.6-3.0), aperture 10A, it can adsorb any molecules which critical diameteris greater than 3.64A and less than 10A, as long as the molecules can be adsorbed by 3A, 4A, 5A type molecular sieve, they also can be adsorbed by 13X molecular sieve. Furthermore, 13X molecular sieve can adsorb bigger critical diameter molecules, such as aromatic hydrocarbons and branched chain hydrocarbons.
Application: Purifying the gas in the air separation device, removal of H2O, CO2 and hydrocarbons; natural gas, liquefied petroleum gas, liquid alkanes (propane, butane) dehydration and desulphurization (removal of H2S and thiol); general gas (such as compressed air, permanent gases) depth drying; ammonia synthesis gas drying and purifying; aerosol, propellant desulfurization and deodorization; pyrolysis gas removal of CO2; catalyst carrier; water and carbon dioxide coadsorption; water and hydrogen sulfide gas coadsorption etc.
