Abstract: The adsorption isotherms of benzene, cyclohexane, p-xylene, m-xylene and o-xylene on HM at 50℃ were determined by vacuum gravimetric method. The order of limiting adsorption on HM (silica-alumina ratio was 15. 8) is benzene>p-xylene>cyclohexane>m-xylene>o-xylene. The adsorption isotherms of benzene and cyclohexane on dealuminated mordenites(silica-alumina ratios were 15. 8, 22. 3, 59. 7, 185. 6) at 50 show that the limiting adsorption of benzene and cyclohexane all decreased with the increase of silica-alumina ratios.
