ABSTRACT:
Alcohol substantially free of water is prepared by fermenting a fermentable biomass feedstock in a fermentation unit, thereby forming an aqueous fermentation liquor containing alcohol; extracting said aqueous fermentation liquor with an organic solvent containing an extractant for said alcohol, thereby forming an alcohol-organic solvent extract phase and an aqueous raffinate; contacting said alcohol-organic solvent phase with a carrier gas thereby separating said alcohol from said alcohol-organic solvent phase and forming an alcohol laden solvent vapor; and separating alcohol substantially free of water from said carrier gas.
