CATALYST AND PROCESS OF OXIDATIVE DEHYDROGENATION OF PROPANE

The present invention relates to catalysts that are selective for the reaction of ODH of propane to propene. Said catalysts are potassium salts of the dodecatungstophosphate ion partially substituted with vanadium and niobium, or mixed oxides of W, V and Nb, with a tungsten bronze structure, obtaine...

Zusammenfassung:	The present invention relates to catalysts that are selective for the reaction of ODH of propane to propene. Said catalysts are potassium salts of the dodecatungstophosphate ion partially substituted with vanadium and niobium, or mixed oxides of W, V and Nb, with a tungsten bronze structure, obtained by thermal decomposition of polyoxometalate salts with a Keggin structure. La présente invention concerne des catalyseurs sélectifs pour réaction ODH de propane à propène. Ces catalyseurs sont des sels de potassium du ion dodécatungstophosphate partiellement substitué par vanadium et niobium, ou des oxydes mixtes de W, V et Nb avec structure de bronze de tungstène obtenus par décomposition thermique de sels de polyoxométallates de structure du type Keggin.
