The molecular sieve on the air separation is currently used more 13X-APG type molecular sieve. The process principle is to use the internal porosity of its particles, and has a strong affinity for polar molecules, selective adsorption of carbon dioxide, water, and some hydrocarbons and other impurities. Activated alumina has high compressive strength, low abrasion rate, no pulverization, no bursting, etc. Its resistance to sudden changes in cold and heat is also very strong, and it also has bett...
