Abstract

This study describes the thermodynamic formulations for the heat of adsorption and the adsorbed phase specific heat capacity from the rigor of classical thermodynamics with the involvement of adsorption parameters. The abovementioned thermodynamic quantities are evaluated from the equilibrium uptakes for adsorption of methane onto different types of activated carbon and found to be strongly dependent on the adsorption parameters along with the pressure and temperature. The adsorption uptake data of methane/Maxsorb III pair for temperatures both in sub-and supercritical regions are also used in the property evaluations and it is observed that the quantities vary with temperature and the trend is opposite between the sub-and supercritical regions.
