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 method1.
Room temperature, humidity ﹤90%,non-expose to air; non-contact with water, acid and alkali.
