The invention relates to a shell catalyst comprising: (a) a support body, (b) a first layer containing a molybdenum oxide or a precursor compound forming molybdenum oxide, (c) a second layer containing a multi-metal oxide containing a molybdenum and at least one other metal. Preferably, the molybdenum oxide of the first layer is MoO3 and the multi-metal oxide of the second layer is a multi-metal oxide represented by general formula (II): Mo12Bi a Cr b X1c Fe d X2 f O y.
L'invention concerne un catalyseur en coquille contenant (a) un corps support; (b) une première couche renfermant un oxyde de molybdène ou un composé précurseur formant de l'oxyde de molybdène; et (c) une deuxième couche renfermant un oxyde multimétallique contenant du molybdène et au moins un autre métal. L'oxyde de molybdène de la première couche est de préférence MoO3, et l'oxyde multimétallique de la deuxième couche est de préférence un oxyde multimétallique représenté par la formule générale (Il): Mo12BiaCrbX1 cFedX2 eX3 fOy.
