Introduction:
Advantages of molecular sieve 4A:
1) With uniform pore size and high surface area, thermal stability, high absorption capacity, high strength characteristics.
2) By molecules of different size and shape, select the adsorption, meaning that just absorb less than the pore size of 4A molecular sieve.(never adsorb any molecular larger than 4A)
3) For small polar molecules and unsaturated molecules, with selective absorption properties, the greater the polarity, the higher the unsaturation, the selective adsorption is stronger.
4)Has strong water absorption. Even at the higher temperature,Greater airspeed and the lower content of water, still have the relatively high water absorption capacity

Reactivation:
1. Removal of water: Hot gas at 200-350°C and pressure 0.3-0.5Kg/cm2 flows through the Zeolite 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.
