3A molecular sieve is an alkali metal silica aluminate, sometimes known as 3A zeolite molecular sieve. Its chemical formula is 2 / 3K2O 1 / 3Na2O Al2O3 2SiO2 9 / 2H2O, and its effective pore size is approximately 3A (1A=0.1 nm). It is mainly used for adsorbing water and does not adsorb any molecules with a diameter greater than 3A. According to the characteristics of industrial application, 3A molecular sieve has fast adsorption speed, regeneration times, crushing strength and anti-pollution ability, which improves the utilization efficiency of molecular sieve and extends the service life of molecular sieve. It is the necessary desiccant for the deep drying, refining and polymerization of gas and liquid phase in the petroleum and chemical industry.
