Adsorption of methanol on sodium faujasites and mordenites

Abstract

Calorimetry and IR spectroscopy were used to study the adsorption of methanol on faujasites and mordenites with different Si/Al ratios. It was shown that the disturbance of the OH bonds in CH3OH weakens and the heat of adsorption decreases as the cation content in the zeolites decreases. The protic acid sites in decationized mordenite form strong hydrogen bonds with the adsorbed molecules.
