Molecular sieve uses physical adsorption and can be reused after being reactivated. It has a strong moisture absorption ability at low humidity, high-temperature resistance, and good stability. Molecular sieve is a kind of alkali metal aluminosilicate, the main types are 3A, 4A, 5A, and 13X. The particle size is 1.5-2.5mm. Among them, the 13X molecular sieve has a pore size of 1 nm and is capable of adsorbing molecules less than 1 nm. It can be used as a catalyst carrier, water, and carbon dioxide co-adsorption, and water and hydrogen sulfide gas co-adsorption.
