Silica-alumina gel（H）
[Characteristics]
Color: faint yellow.
Chemical molecular formula :mSiO2.nAl2O3.XH2O.
Chemically stable ,flame-resisting.Insouble in any solvent except strong alkalia or hydrofluofic 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 commondryer ,catalyst and tis carrier ,variable –pressure adsorption separation agent (PSA). As variable-temperature adsorption separation agent (TSA) at higher temperature, it performs especially suitable.
