CA 2174654

Proposed is a method of producing catalytically active multi-metal oxide compositions containing Mo and V, the method calling for a catalyst precursor compound to be calcined at a temperature of 300 to 450 ~C in an atmosphere consisting of inert gases and/or steam plus 0.5 to 4 % by vol. of O2 and, averaged over the calcination time, 1 to 8 % by vol. of NH3.

Procédé de fabrication de substances formées d'oxydes multimétalliques à activité catalytique renfermant Mo et V, consistant à calciner un précurseur d'un catalyseur à une température de 300 à 450 ~C en atmosphère gazeuse formée de gaz inertes et/ou de vapeur d'eau avec, en plus, 0,5 à 4 % en volume de O¿2? et, en moyenne par rapport au temps de calcination, 1 à 8 % en volume de NH¿3?.
