ABSTRACT:
Process for regenerating a spent catalyst, which catalyst contains potassium, cobalt, nickel, iron, bismuth, phosphorus and molybdenum and sufficient oxygen to satisfy the valence of the other elements therein, on a support, e.g. silicon oxide, wherein at least a portion of the molybdenum has been lost during ammoxidation, comprising impregnating said catalyst with bismuth and molybdenum in solution so that at least some of the molybdenum lost is replaced, e.g., a typical impregnating solution is prepared by dissolving molybdenum trioxide and phosphoric acid in water, adding nitric acid and finally dissolving bismuth nitrate pentahydrate in the resultant solution.
