Combat MS 5A (PSA)
    Publish time 2023-09-15 10:27    

Hydrogen purification molecular sieve Combat MS 5A greatly increased the CO, N2 and CH4 adsorption capacity than standard molecular sieve 5A, which makes it an excellent adsorbents for PSA hydrogen purification process.  Hydrogen purification molecular Sieve 5A have the shape of beads with diameter 1.6-2.5 mm (8x12 mesh).

Combat MS 5A (PSA)


Combat MS 5A (PSA)


Standard molecular sieve 5A is made from zeolite powder 5A (>70%) and binder. Binder is clay, which has little adsorption capacity. Binderless 5A transforms clay binder to zeolite 5A. That means zeolite 5A composition in binderless molecular sieve 5A is 100%, that greatly increased its adsorption capacity. Hydrogen purification molecular sieve Combat MS 5A is normally used in PSA hydrogen purification. Hydrogen purification Combat MS 5A has the advantages of a large adsorption capacity, fast adsorption and desorption rate and high mechanical strength. Hydrogen purification molecular sieve Combat MS 5A greatly increased the CO, N2 and CH4 adsorption capacity than standard molecular sieve 5A, which makes it an excellent adsorbents for PSA hydrogen purification process.  Hydrogen purification molecular Sieve Combat MS 5A have the shape of beads with diameter 1.6-2.5 mm (8x12 mesh).

Hyrogen purification molecular sieve Combat MS 5A can be regenerated or activated either thermal regeneration method (Thermal Swing Adsorption, TSA); To remove moisture from a Hyrogen purification molecular sieve Combat MS 5A, a temperature of 200-230℃ (390-570°F) is required. Hyrogen purification molecular sieve Combat MS 5A can also be regnerated by lowering the pressure in the case of pressure swing processes (PSA). A properly regenerated molecular sieve can give moisture dew points below -100℃. The outlet concentrations on a pressure swing process will depend on the gas present, and on the conditions of the process.
