Industrial color changing blue white orange silica gel water absorption silica gel desiccant
Product Description
Industrial color changing blue white orange Silica Gel water absorption silica gel desiccant
Color: faint yellow.Chemical molecular formula:mSiO2.nAl2O3.XH2O.
Chemically stable,flame-resisting.Insoluble in any solvent except strong alkali or hydroelectric acid. In comparison with fine-pored silica gel ,the adsorption capacity of HY-H silica alumina gel is quite the same when used at low relative humidity ,(e.g.RH=10%,RH=20%),while its adsorption capacity at high humidity is 6—10%higher than that of fine-ported silica gel. Its thermal stability is over 150℃ higher than that of fine-pored silica gel (200 ℃).Ideally suited for use as absorbent and variable-temperature absorbent.
Application
Mainly used of separating light hydrocarbon from natural gas, the product can reduce dew point of hydrocarbon to produce natural gas gasoline , drying natural gas at the same time .Add 20% (wt) HY-W as the protective layer if water drip exits in separation system. In addition,it can be used as common dryer ,catalyst and its carrier ,variable –pressure adsorption separation agent (PSA). As variable-temperature adsorption separation agent (TSA) at higher temperature, it performs especially suitable.
