摘要：

A new molecular model for activated carbons is presented, which consists of a collection of randomly oriented carbon crystallites. The carbon displays energetic heterogeneity as a result of its complex microstructure and surface polarity. Adsorption isotherms and isosteric heats of adsorption for methane, ethane and their binary mixtures were estimated by grand-canonical Monte Carlo simulations. Simulations of the adsorption of water vapor were performed to adjust the surface polarity of the adsorbent.
