Adsorption isotherms of nitrogen and methane were measured on natural clinoptilolite and on stronger adsorption sites. IR spectra of the ƒË1, CH4, for the natural zeolites-methane system suggested that methane molecules are adsorbed on strong cationic sites which corresponds to Na+ and K+ sites for clinoptilolite zeolites and to Ca2+ and Na+ sites for montmorillonite/mordenite zeolite.
