Abstract
The present invention includes a process for the dehydration of ethanol by adsorption of water at elevated pressure and for the regeneration (purging) of adsorbent at a lower pressure than the pressure used for the adsorption of water where the ratio of the duration of the regeneration (purge) step to the duration of the water adsorption step is higher than 0.1 and the temperature of adsorption is greater than 260 degree Fahrenheit.
