- Аннотация: Thermodynamic properties of adsorption systems based on microporous carbon adsorbents of different origin and methane were calculated using methane adsorption experimental data in wide ranges of temperatures and pressures. Molecular dynamics (MD) approach was used for simulation of adsorbate state inside micropores of carbon adsorbents employing the model slit-like shape of pores. Major thermodynamic functions – isosteric heats of adsorption have been calculated using V. Bakaev approach, which takes into account non-ideality of equilibrium gas phase and non-inertness of adsorbent (adsorption-induced and thermal deformation). Other function such as entropies, enthalpies and heat capacities of adsorption systems were also calculated. It was shown that thermodynamic functions could provide important information concerning the state of adsorbate inside micropores at different levels of adsorption value. Obtained results were in good agreement with the data from MD simulation. Finally, integral heats of adsorption of the systems were estimated, which can be used for determination of the thermal properties of scaled adsorption systems during adsorption/desorption processes.
