China 4A Molecular Sieve for Refining Purification

4A Molecular Sieve for Refining and Purification
Production Description:
Molecular sieve 4A is a kind of alkali-metallic silicon-aluminum compounds ,it is the sodium form of the type a crystal structure. Molecular sieve 4A has an effective pore opening of 4 angstroms(0.4nm),4A molecular sieves can absorb the molecules which critical diameter is not more than 4 angstroms, 4A molecular sieves is sued in the dryness of gases and liquid, and absorb H2O,NH3,H2S,SO2,CO2,C2H5OH,C2H6,C2H4,C3H6 and so on,4A molecular sieve is also used for dryness of impurity gas in oil,
Oil & natural gas and dehydration of ethanol, if it lost effectiveness,4A zeolite can be regenerated to reuse
Application:
Deep drying of gases and liquids, such as air,naturalgas,refrigerants,solvents etc.
Drying of saturated hydrocarbons
Refining and purification of argon gas
Static dehydration of electronic element ,pharmaceutical and unstable materials
Material:
Type:4A,Pore diameter:4 angstroms;chemical form:Na2O~AL2O3~2SiO2~9/2H2O(SiO2/AL2O3=2)
