ABSTRACT:
Gasoline aids production of alcohol and fuel in a solvent extraction and recovery process. Alcohol/water mixtures, such as those produced by fermentation of biomass material, are separated by extraction of alcohol with a solvent especially suited to such extraction and to subsequent removal. Conventional distillation steps to concentrate alcohol and eliminate water are rendered unnecessary at a considerable reduction in heat energy requirement (usually met with fossil fuel). Addition of gasoline between the solvent extraction and solvent recovery steps not only aids the latter separation but produces alcohol already denatured for fuel use.
