A volumetric apparatus was used to measure adsorption equilibria for alcohols and their mixtures with water on BPL activated carbon. Pure alcohol isotherms are reported for methanol, ethanol, propanol, and butanol at 25, 50, 75, and 100 C over a large pressure range. Binary equilibria are reported for each alcohol coadsorbed with water at 25 and 100 C including hysteresis for all systems. Enhanced water adsorption was observed in the presence of all alcohols, and enhanced alcohol adsorption was observed for methanol and ethanol. Pure alcohol isotherms are described using a multitemperature Toth equation, and binary equilibria are modeled with the virial mixture coefficient method.
