For quantitative assessment of influence certain factors on the activation process of peach shells, for obtaining its mathematical model, as well as factors definition at which a developed porous structure is achieved, the method of planning and statistical processing experiment was used in the work. The use of effective methods for regulating the porous structure of activated carbon sorbent suggests that it is possible and economically feasible to use them as adsorbents for the treatment of natural and wastewater and gas emissions. The Box-Wilson experimental-statistical method of planning experiment was used. Modeling by the experimental-statistical Box-Wilson method was carried out in three stages: the first stage is a local description of a small section of the response surface by a polynomial of the first degree; the second stage is a steep ascent along the response surface, which is a geometric interpretation of the response function; the third stage is the approximation of the response surface by a polynomial of the second order. In the work, optimization was carried out by the method of steep ascent over the response surface. The solution of the optimization problem and the finding of a second-order equation were considered. As a result of mathematical modeling of the activation process of adsorbents by the experimental statistical Box-Wilson method, optimal factors of the activation process of peach shells with zinc chloride concentration of 38.2% and an activation temperature in the CO2 stream of 743 K were found.
