Introduction:
a kind of alkali aluminosilicate and able to absorb molecules with their critical diameters no more than
Applications:
a) Dry gas, purify raw air material: get rid of H2O and CO2.
b) Desulfurate liquid hydrocarbon and natural gas: get rid of H2S and thioalcohol.
c) Molecules can be adsorbed by molecular sieve
d) Can adsorb molecular whose diameter is a little less than critical diameter, such as some aromatic hydrocarbon and branched-chain hydrocarbon.
Formula: Na2O·Al2O3·2. 45SIO2·6. 0H2O
