1. adsorbent, for utilizing pressure to change absorption method, employed adsorbent during from air manufacturing nitrogen, it is characterized in that having an activated carbon molecular sieve of alternative adsorption of oxygen, it is that the raw material activated carbon of 0.05~

  • 0.12g/g prepares that this activated carbon molecular sieve is to use the benzene adsorbance, begin from oxygen supply, 50% oxygen required time " TO " of absorption saturated oxygen gas adsorbance is 5~

    10 seconds, and begin from nitrogen supply (NS), 50% the nitrogen required time " TN " that adsorbs saturated nitrogen adsorption amount is " TO " 41 times~

    44 times, the CMS under the vacuum is handled afterwards and remains in regeneration, be decided to be 25 ℃

    in temperature, and initial pressure is decided to be under the condition of 26.7kPa, is begun by the supply of gas, and adsorption of oxygen and nitrogen to 50% of the equilibrium adsorption capacity required time is decided to be " TO " and reaches " TN " respectively.
