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.
