Experimental adsorption isotherms on exchanged cation mordenites with and without binder and on different pillared clays have been obtained for different gases such as H(2), D(2), N(2), Ar, CO, CO(2) and CH(4) in a wide range of temperature and pressure. The microstructure of these porous solids has been evaluated quantitatively in terms of pore size distribution (PSD), micropore volume and surface area by analysis and transformation of some of the above isotherms into structural information on the basis of a pore model. Different models of the pores have been considered: the Horvath-Kawazoe or slit model, the cylindrical model and the spherical one. These structural data have been used to predict the adsorptive behaviour of the solid in terms of the characteristic curves of these materials according to the adsorption potential theory and its generalisation.
