The invention relates to a thermally-integrated method for producing butadiene from butanol that comprises at least the following steps:

Integrated method for producing butadiene from butanol

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.

Method for the production of butadiene and hydrogen from ethanol in two low-water and low-energy-consumption reaction steps

The invention concerns a process for the production of butadiene from an ethanol feed comprising at least 80% by weight of ethanol, comprising a step for conversion of ethanol to acetaldehyde, a step for the extraction of butadiene, a step for scrubbing gaseous by-products with water, a step for eliminating impurities and brown oils, a step for treating effluents, a first butadiene purification step, and a subsequent butadiene purification step, said ethanol feed being supplied to said butadiene extraction step, the arrangement of the steps and recycles allowing the recycles to be maximized and allowing the water and energy consumption to be minimized.

Production of 1,3-butadiene ethanol, that is more than 50% of the total weight of feedstock:

Process for producing 1,3-butadiene from a feedstock comprising ethanol

A process for the production of middle-distillate hydrocarbon-containing bases from a butanol feedstock, comprising: a) isomerizing dehydration of butanol feedstock; b) separating the water from butylenic effluent; c) purifying the organic liquid effluent from stage b); d) oligomerizing a feedstock that comprises at least a portion of the purified organic effluent from stage c), the entire effluent from stage g), and at least a portion of the light product from stage f); e) oligomerizing the first oligomerization effluent to produce a second oligomerization effluent; f) fractionating the second oligomerization effluent into at least three products: a light product mostly comprising Cto Ccompounds, an intermediate product mostly comprising Cto Ccompounds, and a middle distillate product mostly comprising compounds having at least 10 carbon atoms; g) oligomerizing at least a portion of the intermediate product, and h) hydrogenating at least a portion of the middle distillate product.
