Abstract
The adsorption characteristics of methane on a Maxsorb II specimen of activated carbon were measured over the temperature range of (281 to 343) K and at pressures up to 1.2 MPa using a new volumetric measurement system. The adsorbent was characterized through properties such as the skeletal density, Brunauer-Emmett-Teller (BET) surface area, and pore-size distribution. The adsorption data were fitted to two isotherm models proposed by Tooth and Dubinin-Astakhov with a predictive accuracy of better than 3 %. The present data were compared with those of various researchers with comparable specimens and found to be consistent with those in the open literature. The present data could complement ..
