Abstract:
A process for the production of butadiene from an ethanol feed having at least 80% by weight of ethanol, A) converting ethanol into acetaldehyde B) converting an ethanol/acetaldehyde mixture into butadiene, C1) hydrogen treatment, D1) butadiene extraction, a first butadiene purification D2), a subsequent butadiene purification D3), an effluent treatment E1), E2) eliminating impurities and brown oils and F) scrubbing with water.
