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.
