Use of fast multivariant identification of the parameters of adsorption systems to study the impact of activating agent on microporous structure formation during activation

The possibility of using fast multivariant identification of adsorption system parameters to evaluate the influence of the activation conditions on the microporous structure of carbonaceous adsorbents was examined. The fitted models used in the procedure are based on a unique approach to the modeling of adsorption processes, which is a significant development of the conventional BET approach. This takes into account the occurrence of branched clusters and surface heterogeneity. The approach considers heterogeneity from the perspectives of both geometry and energy, and discusses geometrical and energy limitations of creating clusters and the adhesive forces in layers above the first one.
