<p>A process for producing lower alcanols from organic residues and effluents such as milk whey, manure, must, wort, straw, peat moss and biomass. This process comprises the steps of: subjecting the residues if any, to hydrolysis; subjecting the effluents and/or hydrolyzed residues to fermentation in the presence of a fermentation initiating agent consisting of amylytic enzymes; adding basic aluminate acetate and a compound selected from the group consisting pyruvic acid, propionic acid and mixtures of formaldehyde with phenol or sulfonated phenol to the fermented effluents of the first step; heating the mixture obtained in the second step at a temperature ranging between 120.degree.C and 160.degree.C under a pressurization of at least 1.5 kg/cm2 until the requested alcanols are produced; and recovering the produced alcanols by distillation.</p> |
