5A Molecular Sieve
A kind of alkali-metallic, silicon-aluminum compounds, It is calcium form of type A crystal structure.
It could absorb the molecules which critical diameter is not more than 5 angstroms.it can also adsorb C3—C4 normal alkanes, ethyl chloride, ethyl bromide, butanol, etc. It can be used in normal iso-hydrocarbon separation, pressure swing adsorption separation and water Co-adsorption with carbon dioxide.
Chemical Molecular Formula:
0.7CaO·0.3Na2O·Al2O3·2SiO2·4.5H2O. (SiO2 : Al2O3 ≈2).
