Summary

This project involves the characterisation and modification of clays obtained at Serra de Dentro, Porto Santo Island, for application as catalysts in important liquid phase organic reactions. The team of Universidade de Évora investigates the alterations in structure, surface area and porosity, resulting from various modification treatments, namely: cationic exchange with Na, Al, Ca, Cr, Ni or Fe ions; pillaring with Al-, Cr- and mixed metal Al/Cr oxides; acid activation at different temperatures, contact time and concentration. These studies are carried out by powder X ray diffraction, FTIR, nitrogen adsorption at 77K, n-pentane adsorption at 298K and by the n-nonane pre-adsorption method.
