It is a calcium potassium type aluminosilicate with a crystal pore size of 5A (0.5nm), which can adsorb any molecule smaller than this pore size. It is mainly used for the separation of isomers, pressure swing adsorption separation, and co adsorption of water and carbon dioxide. Based on the industrial application characteristics of 5A molecular sieve, our 5A molecular sieve has high adsorption capacity, fast adsorption speed, and is particularly suitable for pressure swing adsorption. It can adapt to various sizes of gas pressure swing adsorption devices such as oxygen production, hydrogen production, and carbon dioxide production, and is a boutique in the pressure swing adsorption industry
