Description:
It is chemically stable, non-flammable, and insoluble in any solvents except strong and hydrofluoric acid. Compared with fine-pored silica gel, the low-humidity adsorption capacity is equivalent (such as RH=10%, RH=20%), but the high-humidity adsorption capacity (such as RH=80%, RH=90%) is 6-10 higher than that of fine-pored silica gel, the thermal stability (200℃) is higher than that of fine-pored silica gel by more than 150℃, which is very suitable for temperature swing adsorbent and separating agent.

Application:
Used to separate flammable hydrocarbons from natural gas, reduce the dew point of hydrocarbons, and produce natural gas gasoline. The natural gas is also dried. If water droplets appear in the separation system, about 20% (weight ratio) of GC-W silica-alumina gel should be added as a protective layer.
Package:
25kg/compound bag: 150kg steel drum; 800kg super sack.
