Propertities:
The appearance of aluminum silica gel is silightly yellow or white transparent with chemical molecular formula mSiO2 • nAl2O3.xH2O. Stable chemical propertities. Non combustion, insoluble in any solvent except strong base and hydrofluoric acid. Compared with fine porous silica gel, the adsorption capacity of low humidity is similar (such as RH = 10%, RH = 20%), but the adsorption capacity of high humidity (such as RH = 80%, RH = 90%) is 6-10% higher than that of the fine porous silica gel, and the thermal stability (350℃） is 150 ℃ higher than fine porous silica gel. So it is very suitable to be used as the variable temperature adsorption and separation agent.
Application:
It is mainly used to separate light hydrocarbon from natural gas, reduce the dew point of hydrocarbon, and produce natural gas and gasline, meanwhile, the natural gas is also dried. If there is water droplet in separation system, it needs about 20% (weight ratio) of water-resistant Si-Al-silica gel as protective layer.
This product can also be used as a common desiccant, catalyst and its carrier, also can be used as PSA, especially suitable for high temperature TSA.
