description This article covers the results of a study on the determination of the differential heat, isotherm and entropy of water vapor in ZSM-5 zeolites at a temperature of 303 K using the adsorption-calorimetric method. The type and number of ion-molecular formed complexes, as well as the mechanism of adsorption of the studied molecules, were determined. By studying their energetic properties, it is possible to determine the chemical composition and crystal structures of the zeolites. The adsorption isotherm was described by two-and three-had mathematical equations of the TVSM (the theory of volumetric saturation of microgroups) from the beginning to saturation. An analysis of the obtained results proved that NH4ZSM-5 and NZSM-5, which are used as catalysts, can be used as zeolites.
