    摘要： The invention relates to a process for producing 1,3-butadiene from an ethanol-rich feedstock, i.e. in which the ethanol represents more than 50% of the total weight of said feedstock, comprising at least: A) a step of converting at least said ethanol-rich feedstock and the ethanol effluent resulting from the separation step B into a conversion effluent predominantly comprising 1,3-butadiene, water and ethylene, and into a hydrogen effluent, operating at a pressure between 0.1 and 1.0 MPa, at a temperature between 300°C and 500°C in the presence of at least one catalyst; B) a step of separating at least said conversion effluent resulting from A and the hydration effluent resulting from C into at least an ethanol effluent, a butadiene effluent, a water effluent and an ethylene effluent; C) an ethylene hydration step supplied at least by said ethylene effluent and/or said water effluent both resulting from the separation step B, in order to produce a hydration effluent comprising ethanol, said hydration effluent then being recycled to the separation step B.

    摘要： The invention relates to a thermally integrated method for producing butadiene from butanol, which includes at least the following steps: a) dehydrating butanol, which process is supplied by a dehydration supply made up of at least said n-butanol feedstock diluted with at least a portion of the purified-water effluent from step c), resulting in a butene effluent in at least one reactor, in the presence of a catalyst including an alumina; b) oxidatively dehydrogenating said butene effluent, diluted with at least a portion of the purified-water effluent from step c), into butadiene, said butene effluent not having been treated in any way after dehydration step a); and c) separating the effluent obtained from step b) into at least one butadiene effluent and one purified-water effluent.
