Abstract (en)

[origin: WO2017009106A1] The invention relates to a catalyst including at least the element tantalum, at least one aldol-reaction element and at least one mesoporous oxide matrix, the mass of tantalum making up from 0.1 to 30% of the mass of the mesoporous oxide matrix, the mass of the at least one aldol-reaction element making up from 0.02 to 4% of the mass of the mesoporous oxide matrix, and to the use thereof to convert ethanol into butadiene.
