  • Low energy process of producing gasoline-ethanol mixtures
    Patent number: 4297172
    Abstract: Gasoline-ethanol mixtures useable as motor fuel are produced by a relatively low energy process comprising interrelated distillation and extraction steps. In the first step, aqueous ethanol, such as an ethanol fermentation beer, is subjected to fractional distillation to produce a distillate of at least 75 weight percent ethanol, which is then subjected to extraction with gasoline under conditions producing an extract containing the desired amount of ethanol, such as 8 to 14% by weight. The aqueous phase raffinate from the extraction is returned to the fractionation column for redistillation.
