5A molecular sieve can adsorb any molecule smaller than its pore size, and is generally called calcium molecular sieve. In addition to the functions of 3A and 4A molecular sieves, it can also adsorb C3-C4 normal alkanes, ethyl chloride, ethyl bromide, butanol, etc., and can be used for N-isomeric hydrocarbon separation pressure swing adsorption separation, and co-adsorption of water and carbon dioxide. Based on the industrial application characteristics of 5A molecular sieve, the 5A molecular sieve we produce has high selective adsorption, fast adsorption speed, and is particularly suitable for pressure swing adsorption. It can adapt to various volumes of oxygen generation, hydrogen generation , carbon dioxide generation and other gas pressure swing adsorption.
Chemical formula : 3/4CaO·1/4Na2O·Al2O3·2SiO2·9/2H2O
Silicon-aluminum ratio : SiO2/Al2O3≈2
Effective pore size : about 5A (0.5 nm)
It mainly used for separation of N-isomeric hydrocarbon separation , separation of oxygen and nitrogen, drying and refining of chemical, petroleum and natural gas, ammonia decomposition gas and other industrial gases and liquids.
