설명

일반 설명

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.

애플리케이션

Molecules with an effective diameter of 4 Å, including H₂O, H₂S, CO₂, SO₂, C₂H₄ and C₃H₆ are adsorbed.
