FIELD: chemistry.
SUBSTANCE: in method of reduction of water, CO2 and N2O in raw material air applied is first adsorbent, such as aluminium oxide (25-40 vol %), and second adsorbent, such as zeolite X (60-75 vol %); time of adsorbent work is determined by determination of concentration, measured by means of analyser for concentration of CO2 in position within the range of second adsorbent length, when maximal N2O level is obtained simultaneously on lower by stream end of second adsorbent in direction of supply, where time of work is the time from the start of raw material air passage into first and second adsorbents before measuring by analyser of certain CO2 concentration; at least, second adsorbent is regenerated by means of heated regeneration gas at temperature from 140 to 220°C and molar ratio of regeneration gas to raw material air, supplied for one cycle iteration, constitutes 0.08-0.5.
EFFECT: increase of air purification degree.
