Abstract
Water sorption isotherms on natural chabazite modified with an organic binder are reported. As expected, samples showed type I IUPAC isotherms. The applicability of potential theory and the Dubinin equation was examined. A temperature-independent characteristic curve was obtained by introducing the reduced adsorption potential. This successful correlation gives the possibility of predicting adsorption isotherm points at any temperature and pressure. Kinetic tests were made to establish the temperature and pressure dependence of the diffusivity parameter.File in questo prodotto:
