✦ Synopsis
A new numerical procedure, based on the simulated annealing algorithm (SA), for optimizing the parameters of a new recently developed gamma-type adsorption isotherm equation is proposed. This procedure is verified for three modeled adsorption isotherms assuming some arbitrarily chosen shapes of the pore size distribution function (asymmetrical bell-shaped functions possessing one or two points of inflection and decreasing to a zero-hyperboliclike function).To study the properties of the presented algorithm, several different models of temperature decrease were tested. It is shown that the best results are obtained for the models of temperature decreasing rapidly. Additionally, the SA algorithm provides (in a very short time) values of the optimization parameters that are very close to the global minimum of the fitness function.
From the practical point of view, the obtained results are satisfactory and the proposed method can be successfully applied to determining the parameters of the microporous structure of activated carbons.
