Abstract (en)
[origin: WO2022002624A1] The present invention relates to a method for producing alcohols comprising: a. a step of IBE fermentation in at least one bioreactor (R1) in the presence of a microorganism of natural strain, and fed at least by an aqueous solution (1) of C5 and/or C6 sugars and a recycled acetone stream (3), to produce fermentation gases and a fermentation must containing fermentation products; b. a step of recovering the fermentation products, to obtain a stream of fermentation products (2); c. a step of treating the stream of fermentation products comprising a section for separating the acetone in order to produce at least one acetone effluent (3) and an aqueous effluent of alcohols (4); d. a step of recycling at least one fraction of the acetone effluent (3) from step c) to step a).
