摘要：
The kinetics of nonisothermal adsorption from a limited volume with consideration of the dependence of the differential heat of adsorption and the intracrystalline diffusion coefficient on the degree of filling were mathematically modeled. A model of the adsorption kinetics which explains the appearance of extremes on the experimental kinetic adsorption curves in adsorption of water by CaA zeolite was proposed. It was shown that a decrease in the differential heat of adsorption with an increase in the degree of filling is a necessary condition for the appearance of extremes on the kinetic adsorption curves.
