5A molecular sieve

Uses: In addition to adsorbing 3A and 4A adsorbed molecules, it is used for co-adsorption of isomeric hydrocarbons, oxygen and nitrogen separation and CO2-H2O. It is especially suitable for pressure swing adsorption. It can be adapted to various sizes of oxygen, hydrogen, carbon dioxide and other gases. It is mainly used for drying and refining chemical, petroleum and natural gas, ammonia decomposition gas and other industrial gas liquids.
