Molecular Sieve

Petrosadid: Molecular Sieve

Molecular Sieves are zeolite-based adsorbents with pores of uniform size consisting of clay and zeolites (crystalline aluminosilicates). Zeolites distinct porous structure make them able to adsorb water or other molecules. They are suitable for the absorption of gases or liquids. The pore diameters size is similar to small molecules. Consequently, large molecules cannot be adsorbed or enter. Molecular Sieve have a wide variety of uses in gas and petrochemical purification process.

Based on the application, Petrosadid offers a wide range of molecular Sieve.
