Investigation of the porous structure and adsorption properties of activated anthracite

The porous structures of activated anthracite and AG 3 and SKT standard act ivated carbons are investigated by adsorption-desorption isotherms of benze ne and water vapors. It is established that structural parameters of these adsorbents are within the range characteristic of commercial activated carb ons for adsorption of gases and vapors. It is shown that, in comparison to the reference samples, activated anthracite is characterized by a greater a dsorption volume of micropores, a developed mesoporous structure, and a low concentration of active sites. The efficiency of the activated carbons und er investigation in purification of air from organic impurities is estimate d from data on the kinetics and the dynamics of adsorption of acetone and b enzene vapors from air. Activated anthracite is found to be the most promis ing adsorbent for these purposes.
