METHOD FOR ADSORBING NITROGEN FROM GAS MIXTURE BY USING PRESSURE PENDULUM ADSORPTION WITH ZEOLITE

摘要

Process for selective absorption of N2 from gas mixts. with few polar gas components at 20-50 degrees C using pressure polar gas components at 20-50 degrees C using pressure swing adsorption comprises feeding the gas mixts. through the adsorber filled with zeolite granules. The novelty is that the adsorber comprises two charges: a Na-zeolite X adsorbent in the inlet zone and a Li-zeolite X adsorbent in the outlet zone.
