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. lettemperature decreases down to 110-180°C, cooling.

2. Removal of organics: Regeneration is achieved by means ofsteam treatment to remove organics, and then remove water withmethod 1.

Conservation:

Room temperature, humidity <90%, non-expose to air; non-contactwithwater, acid and alkali..

Packing:
