3A molecular sieve Chemical Formula:2/3K2O?/3Na2O稟l2O3?SiO2?/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 200-350 degree C and pressure 0.3-0.5kg/cm2 flows through the molecular sieve bed for 3-4 h. let temperature decreases down to 110-180 degree C, cooling. 2. Removal of organics: Regeneration is achieved by means of steam treatment to remove organics, and then remove water with method 1. Conservation: Room temperature, humidity below 90%,non-expose to air; non-contact with air, acid and alkali. Packing: 25kg (10 gallon) steel pail 150kg (55 gallon) steel pail.
