Methane recovery from coal mine gases using carbonaceous adsorbents

Commercial active carbons and carbon molecular sieve were examined as adsorbent for methane recuperation. The diameter and volume of micropores in the adsorbents studied were evaluated by the molecular probe method. A test was developed to assess the suitability of adsorbents for needs of methane recovery from gaseous mixtures using PSA technique. The relationship between adsorption of methane from gas mixture and texture parameters characterizing the carbonaceous adsorbents was found.
