4. Simultaneous characterization of micropores and mesopores

In recent years, a great deal of work has been carried out in the field of adsorption modeling and simulation, leading to a better description of the adsorption phenomenon and, consequently, of adsorbents. These calculations do not use Kelvin's law, nor any equation such as that of Harkins and Jura, which gives the thickness of the multimolecular layer as a function of pressure and is assumed to be "universal"; they are based on a set of reference adsorption isotherms calculated, for a set of pores of different sizes, by numerical simulation methods (Monte-Carlo), or by DFT (§ 1.2
