N2 - The adsorption isotherm of an adsorbate-adsorbent pair is the key information for storage capacity and thermal management of adsorptive gas storage system. This article presents the adsorption isotherm of methane, which is the major component of natural gas, on pitch-based activated carbon type Maxsorb III for a wide range of temperature (120 to 350) K and pressure up to 2.5 MPa. The uptake values have been experimentally measured using volumetric technique. Since the Maxsorb III sample is highly microporous and heterogeneous in surface structure, the popular Toth isotherm model is used to fit the data due its accountability of the heterogeneity parameter. The measured uptake data are useful to estimate the charge pressure of adsorbed natural gas storage system at different adsorbent temperature for constant adsorption capacity.
