Reactivation:
1. Removal of water: Hot gas at 200-350°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°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 <90%, non-expose to air; non-contact°°with°°water, acid and alkali..
Packing:
25 Kg (10 gallon) steel pail
150 Kg (55 gallon) steel pail
