Abstract[English]
Methods for preparing a catalyst are provided. An exemplary method includes forming a slurry including metal oxides, a reducing agent, and water; and heating the slurry to form the catalyst. The metal oxides include an oxide of molybdenum; an oxide of vanadium; an oxide of tellurium or an oxide of antimony, or both; and an oxide of tantalum 5 or an oxide of niobium, or both. A ratio of the water in the slurry to amount of catalyst formed is between 0.1 mL water per gram of catalyst and 10 mL water per gram of catalyst.[French]
L'invention concerne des procédés de préparation d'un catalyseur. Un procédé donné à titre d'exemple comprend la formation d'une suspension comprenant des oxydes métalliques, un agent réducteur et de l'eau ; et le chauffage de la suspension pour former le catalyseur. Les oxydes métalliques comprennent un oxyde de molybdène ; un oxyde de vanadium ; un oxyde de tellure ou un oxyde d'antimoine, ou les deux ; et un oxyde de tantale ou un oxyde de niobium, ou les deux. Un rapport de l'eau dans la suspension à la quantité de catalyseur formée est compris entre 0,1 mL d'eau par gramme de catalyseur et 10 mL d'eau par gramme de catalyseur.
