Abstract

Ethanol may be separated from a feed mixture comprising ethanol and water by contacting said feed mixture with an adsorbent comprising a shaped replication of particle aggregates comprising carbonaceous pyropolymers containing recurring units of at least carbon and hydrogen atoms at a temperature in the range of from about 20.degree. to about 230.degree. C. and a pressure in the range of from about atmospheric to about 500 psig, selectively adsorbing substantially all of the ethanol to the substantial exclusion of water and thereafter recovering high purity ethanol by passing a desorbing material over the adsorbent.
