Description

*3X molecular sieve, also called Natrium X molecular sieve, Zeolite *3X, 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. *3X molecular sieve silicon aluminum ratio≈2.**3.0 (SiO2/Al2O3≈2.**3.0), aperture *0A, it can adsorb any molecules which critical diameteris greater than 3.*4A and less than *0A, as long as the molecules can be adsorbed by 3A, 4A, 5A type molecular sieve, they also can be adsorbed by *3X molecular sieve. Furthermore, *3X 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.
