| Description: | 3A Molecular Sieve Chemical Formula: 2/3K2O· /3Na2O· Al2O3· 2SiO2· 9/2H2O Si/Al ratio: SiO2/ Al2O3=2 Pore diameter: About 3A Use: Used as desiccant in petrochemical, pharmaceutical and other industries. Reactivation: 1. Removal of water: Hot gas at 200-350º Cand pressure 0.3-0.55kg/cm 2 flows through the molecular sieve bed for 3-4 hours. Let temperature decreases down to 110-180º C, cooling. 2. Removal of organics: Regeneration is achieved by means of steam treatment to remove organics, and then remove water with method 1.
