Molecular Sieve 5a Catalyst For N2 O2 H2 Production
Introduction
5A is generally an alkali alumino silicate with the effective pore size of 5 angstrom. 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 straightand 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 the number of industries and applications. An extremely pure hydrogen product is attained using the PSA hydrogen purification procedure.

Application
a) The strong ionic forces of the divalent calcium ion make it an excellent adsorbent to remove water, CO2, H2S from sour natural gas streams, while mini missing COS formation. Light mercaptans are also adsorbed.
b) Separation of normal- and iso paraffins.
c) Production of high purity N2, O2, H2 and inert gases from mixed gas streams
d) Static, (non-regenerative) dehydration of insulating glass units, whether air-filled or gas-filled.
Storage
Avoid moisture, avoid scrolling, throw and sharp shocking during transportation, rainproof facilities should be readied.
It should be stored in dry and ventilated warehouse to prevent contamination or moisture.
