Carbon Molecular Sieve
PSA (pressure swing adsorption) nitrogen generation is implemented by the selective adsorb characteristic of CMS, and different adsorption capacities under different pressure. When pressure rises, the oxygen will be absorbed by molecular sieve material because of its faster expansion speed in the micropore structure of CMS, thus oxygen gas and nitrogen gas are separated. While pressure reduces, the oxygen is desorbed, and CMS regenerated. This cyclic operation lets the nitrogen generation in succession.
|Model||Grain diameter||Bearing strength||Pile proportion||Test temperature||Absorption periods||Adsorption Pressure||Purity(%)||Productivity (Nm3/h.t)||Nitrogen recovery（%）(N2、Air)|
