Characteristics：
Color：faint yellow．
Chemical molecular formula：mSiO2．nAl203．xH20．
Chemically stable，flame-resisting．Insoluble in any solvent except strong alkalia or hydrofluoric 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．
Use：
Mainly used for separating light hydrocarbon from natural gas，the product can reduCe dew Doint Of
hydrocarbon to produce natural gas gasoline，drying natural gas at the same time．Add 20％fwtl HY．
W as the protective layer if water drip exits in separation system．In addition，it can be used as cOmmon duer，catalyst and its carrier，variable-pmssure adsorption separation agent rPSA)．As variable-temperature
adsorption separation agent(TSA)at higher temperature，it performs especially suitable．
we can supply the products according to the customers' requirments and technical index.
