This article highlights the study on the determination of differential heat, isotherm, thermokinetics and entropy of water, carbon dioxide, normal heptane, benzene, methanol, ethanol adsorption on ZSM-5 zeolites, using adsorption-calorimetric method at a temperature of 303 K. The type and number of formed ion-molecular complexes, as well, the mechanism of adsorption of the studied molecules were ascertained. In the zeolite structure, thermokinetics of adsorption and the discovery of the migration laws of exchange cations are considered the adsorption energy of gases and vapors in a flawless zeolite. From the beginning to the saturation, the adsorption isotherm was described by the two- and three-term mathematical equations of STMP.
