General description
Molecular sieves are made up of three dimensional interconnecting networks of silica and alumina tetrahedral. These crystalline metal aluminosilicates have uniform cavities to selectively adsorb specific size molecules. A 4A molecular sieve has an effective pore size of 4Å.
Application
Molecules with an effective diameter of 4 Å, including H2O, H2S, CO2, SO2, C2H4 and C3H6 are adsorbed.
