Abstract: The invention relates to a process for preparing a catalyst for alkane oxidative dehydrogenation and/or alkene oxidation, which catalyst is a mixed metal oxide catalyst containing molybdenum, vanadium, niobium and optionally tellurium, wherein the process comprises: a) preparing a catalyst precursor containing molybdenum, vanadium, niobium and optionally tellurium; b) optionally contacting the catalyst precursor obtained in step a) with oxygen and/or an inert gas at an elevated temperature; c) contacting the catalyst precursor obtained in step a) or step b) with a gas mixture comprising ammonia and water, which gas mixture further comprises oxygen and/or an inert gas, at an elevated temperature; and d) optionally contacting the catalyst precursor obtained in step c) with an inert gas at an elevated temperature. Further, the invention relates to a catalyst obtainable by said process and to a process of the oxidative dehydrogenation of an alkane containing 2 to 6 carbon atoms and/or the oxidation of an alkene containing 2 to 6 carbon atoms wherein said catalyst is used.

Abstract: The invention relates to a method for preparing a hydrogenation catalyst or catalyst precursor comprising a catalytically active material and a carrier material. The method involves the mixing of an acidic solution comprising metal ions of a metal selected from the IUPAC group 8, 9 or 10 metals, preferably cobalt, a suspension comprising the carrier material and an alkaline solution. The invention also relates to a precursor of a hydrogenation catalyst wherein the precursor comprises crystallites of metal oxides having an average size of max. 8 nm.
