Abstract

The invention relates to a method for obtaining ethanol from a carbohydrate-containing raw substrate wherein the ethanol that is produced is separated during fermentation using a carrier gas. The invention further relates to the adsorption of the ethanol from the gas phase to an adsorber, the desorption of the ethanol during a subsequent process step, and to the further concentration of the ethanol.
