ABSTRACT:
A process is described for the preparation of catalysts based on molybdenum and iron oxides which comprises their controlled precipitation in an aqueous medium from sodium molybdate and a soluble ferric salt, the separation and the washing of the precipitate until its sodium content is reduced to less than 150 ppm. According to one embodiment, the sodium molybdate used as the reagent results from the action of aqueous sodium hydroxide on the spent catalyst.
