5A is generally an alkali aluminosilicate with the effective pore size of 5 angstroms. It is suitable for PSA hydrogen purification where unwanted moisture and gases are adsorbed to obtain pure hydrogen. 5A is specialized in sorting out the straight and branch chained hydrocarbons from each other. 5A adsorbent is highly recommended to produce high purity hydrogen from the mixed gas streams. In PSA process of purification, the impurities present in hydrogen get adsorbed to the 5A molecules at high pressure. The molecular sieve in beads and pellets are used based on their available sizes and your requirements. The hydrogen purified after the PSA process plays an important role in a number of industries and applications. An extremely pure hydrogen product is attained using the PSA hydrogen purification procedure.
5A zeolite adsorbent can be regenerated either through the thermal swing process or by decreasing the pressure in the pressure swing process. Temperature from 250 degrees – 300 degrees Celsius is needed to remove the moisture from molecular sieve. The outlet concentration depends on the kind of gas present as well as on the circumstances of the process.
