Reactivation:
1. Removal of water: Hot gas at 180-350°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-exposing in air; non-contact with water, acid and alkali.. Packing:
25 Kg (10 gallon) steel pail
140 Kg (bead, 55 gallon) steel pail
125 Kg (pellet, 55 gallon) steel pail
