PROCEDE DE PRODUCTION DE BUTADIENE ET D'HYDROGENE A PARTIR D'ETHANOL EN DEUX ETAPES REACTIONNELLES A FAIBLE CONSOMMATION EN EAU ET EN ENERGIE
摘要:
The invention relates to a method for the production of butadiene from an ethanol feedstock containing at least 80 wt.-% ethanol, comprising at least: a step A) of converting the ethanol into acetaldehyde, a step B) of converting an ethanol/acetaldehyde mixture into butadiene, a step C1) of treating the hydrogen, a step D1) of extracting the butadiene, a first step D2) of purifying the butadiene, a subsequent step D3) of purifying the butadiene, a step E1) of treating the effluent, a step E2) of eliminating impurities and brown oils, and a step F) of washing with water.
