Abstract

Different potential models for methane and ethylene are tested for their suitability for the description of bulk phase behavior, including coexistence, and adsorption on a graphite surface under sub- and super-critical conditions using GCMC simulation. Under sub-critical conditions, those intermolecular potential models that describe correctly the vapor–liquid equilibria were found to be adequate for the description of surface adsorption. These potential models can also give a good account of adsorption under supercritical conditions or near-critical conditions, provided the experimental data (in terms of excess) are correctly obtained with the reliably determined void volume as illustrated in this paper with methane adsorption.
