The adsorbents for hydrogen production generally use 5A molecular sieve, silica gel, activated carbon, alumina, etc. After many times of research and improvement, screening, strength, life, dynamic adsorption of impurities, separation efficiency and other aspects of performance have reached the world's advanced level. The recovery rate can reach 90%
5A Molecular Sieve
5A molecular sieve can adsorb any molecule smaller than the pore, generally called calcium molecular sieve. In addition to the functions of 3A and 4A molecular sieves, it can also adsorb C3-C4 n-alkanes, ethyl chloride, ethyl bromide, butanol, etc. It can be used in the separation of n-isomeric hydrocarbons, pressure swing adsorption and water co-adsorption with carbon dioxide.
