GARCIA, Andrés A; MORENO, Juan C; GARCIA, Jesús A  and  GIRALDO, Liliana. EVALUATION OF THE CALCULATION OF MICROPORES VOLUME IN THE STUDY OF METHANE ADSORPTION ON ACTIVATED CARBONS.. Rev.Colomb.Quim. [online]. 2007, vol.36, n.1, pp.109-120. ISSN 0120-2804.

Different methods for micropore volume calculation in carbonaceous materials were studied. It was investigated a method which approximates the micropore volume calculated from high pressure methane adsorption isotherms by means of low pressure adsorption isotherms (N₂ and CO₂ ). The best fit was achieved for the Dubinin-Astakhov equation for carbon dioxide isotherms, CO₂, at 273 K.

Keywords : methane adsorption; adsorption parameters; comparison of isotherms.
