FIELD: chemistry.
SUBSTANCE: invention relates to chemistry and can be used in extraction and purification of hydrogen. A gas mixture contaminated with impurities is brought into contact in an adsorption zone having an adsorbent which contains zeolite X powder with varying particle-size distribution coefficient from 15% to 30%.
EFFECT: invention increases hydrogen extraction ratio.
