摘要
The invention relates to a method for producing alcohol from cellulosic material, comprising carrying out hydrolysis of said cellulosic material with an aqueous acid to obtain a hydrolysis product; extracting acid and water from said hydrolysis product with a water-soluble organic extraction solvent to obtain (a) a first aqueous acidic solution containing said extraction solvent and (b) a sugar-containing residue; processing the specified residue in accordance with the reaction of cleavage of oligosaccharides to obtain an aqueous solution of fermentable sugars; fermenting said fermentable sugars and distilling off alcohol from the resulting fermented mixture; contacting said first aqueous acidic solution with a water-immiscible liquid lipophilic solvent to obtain a second aqueous acidic solution and a mixture of said extraction solvent and said liquid solvent; separating said mixture of solvents to obtain an extraction solvent for recycling; and separating from said second aqueous acidic aqueous acid solution for recycling.
