STABILISED PRODUCTION OF 1,3-BUTADIENE IN THE PRESENCE OF A TANTALUM OXIDE STIMULATED BY AN ALDOL-REACTION ELEMENT

摘要

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.
