13X molecular sieve
13X molecular sieve
UOP Molsivtm 13A Adsorbent
Cation: sodium
Chemical formula: na2o*al2o3* (2.8 ± 0.2) sio2* (6-7) H2O
Silicon aluminum ratio: sio2/al2o3 ≈ 2.6-3.0
Effective aperture: about 9
Application: mainly used for gas drying and purification, purification of feed gas of air separation unit (removing H2O at the same time
And CO2), desulfurization of liquid hydrocarbons and natural gas (removal of hydrogen sulfide and mercaptan), catalyst carrier.

Regeneration:
1. Moisture removal: it depends on the temperature, pressure and water content of regeneration gas. Generally, the dry gas at 180~350 ℃ passes through the molecular sieve bed for 3~4 hours under the pressure of 0.30.5kg/cm2 to cool the outlet temperature to 110~180 ℃.
2. Organic matter removal: replace organic matter with steam, and then remove water.
Storage:
Room temperature; The relative humidity is not more than 90%; It is not suitable to be directly exposed to the air; Avoid water, acid and alkali.
