Abstract[English]
Methods for preparing catalysts for oxidative dehydrogenation (ODH) of alkanes such as ethane are provided An exemplary method includes providing a first mixture including metal oxides; a reducing agent; and one or more of a bismuth compound, an antimony compound, and a tellurium compound; and heating the first mixture to form the catalyst. The first mixture is essentially free of water. The metal oxides include an oxide of molybdenum and an oxide of vanadium. The bismuth compound includes bismuth oxide, bismuth hydroxide, or a bismuth carbonate. The antimony compound includes an oxide of antimony, antimony acetate, or antimony ethoxide. The tellurium compound includes tellurium dioxide.[French]
La présente invention concerne des procédés de préparation de catalyseurs pour la déshydrogénation oxydative (ODH) d'alcanes tels que l'éthane. Un procédé donné à titre d'exemple consiste à fournir un premier mélange contenant des oxydes métalliques ; un agent réducteur ; et un ou plusieurs éléments parmi un composé de bismuth, un composé d'antimoine et un composé de tellure ; et à chauffer le premier mélange pour former le catalyseur. Le premier mélange est essentiellement sans eau. Les oxydes métalliques comprennent un oxyde de molybdène et un oxyde de vanadium. Le composé de bismuth comprend de l'oxyde de bismuth, de l'hydroxyde de bismuth ou un carbonate de bismuth. Le composé d'antimoine comprend un oxyde d'antimoine, de l'acétate d'antimoine ou un éthoxyde d'antimoine. Le composé de tellure comprend du dioxyde de tellure.
