Execution standard: National Standard of the People's Republic of China GB/T 2524-2010 "4A Molecular Sieve"
4A molecular sieve is an alkali metal aluminosilicate with the molecular formula Na2O · Al2O3 · 2SiO2 · 9/2H2O. It has the characteristics of high strength, low wear, large adsorption capacity, and strong stability. It can adsorb molecules with critical diameters not exceeding 4A such as H2O, NH3, H2S, SO2, C2H5OH, C2H6, C2H4, etc. It is one of the most widely used molecular sieve varieties in industry.
