| Abstract: | The adsorption isosteres and isotherms of methane on the microporous carbon adsorbent PAU-10 were calculated using the Dubinin—Radushkevich equation taking into account nonideality of the gas phase. The conditions under which the adsorption isosteres are linear were outlined. The calculated and experimentally found adsorption isosteres were compared for the methane—PAU-10 system. The slope of the isosteres remains unchanged on going to the region of strong nonideality of the gas phase. Published in Russian in Izvestiya Akademii Nauk. Seriya Khimicheskaya, No. 3, pp. 382–385, March, 2007. |
