Abstract
Process for dehydrating aqueous ethanol, utilizing a high-pressure distillation (with a single distillation column) of an aqueous ethanol admixture (preferably one derived from a conventional ethanol fermentation process), to achieve a vapor phase ethanol-water admixture containing about 90 percent, by weight, of ethanol, and then drying the vaporous admixture, in the presence of CO.sub.2, with a crystalline zeolite type 3A, utilizing the 'pressure energy' derived from the distillation to allow the product ethanol to condense at ambient temperatures, and then, if desired, employing the resultant dried ethanol product in the production of gasohol.
