- Reactivation:
1. Removal of water: Hot gas at 200-350℃ and pressure 0.3-0.5㎏/㎝2 flows through the molecular sieve bed for 3-4 h. let temperature decreases down to 110-180℃, 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 air, acid and alkali.
- Packing:
25kg (10 gallon) steel pail 150kg (55 gallon) steel pail.
