DEESIDRATACAO EM FASE DE VAPOR A ALTA TEMPERATURA DE MISTURAS ALCOOLICAS AQUOSAS

摘要

Process for the enrichment of aqueous alcohol mixtures comprising contacting the aqueous alcohol mixture while in the vapor state with dried starch having a temperature in excess of about 105 DEG C under conditions effective for water in the vapor to be adsorbed by the starch and thereby produce an alcohol enriched vapor, and recovering the alcohol enriched vapor.
