Popis:	The binary isotherms of mixtures of carbon dioxide and 2% methanol on silica and octadecyl-bonded silica (ODS) were measured at three temperatures over a range of pressures up to 150 bar. Binary isotherms of pure CO 2 and mixtures of 2-4% methanol in CO 2 on the same adsorbents were determined at 50°C. The effects of temperature, pressure, and composition on the adsorption of both methanol and CO 2 were determined over a range of conditions with supercritical fluid mobile phases
