Abstract: In order to increase the amount of catalytic metal which can be incorporated in a zeolite catalyst by contact of zeolite with solution of a given amount of chemical containing the catalytic metal, or conversely to reduce the amount of such chemical needed to incorporate a given desired amount of catalytic metal in the catalyst, a zeolite containing a cation, e.g., sodium, replaceable by ammonium ion, is contacted with an aqueous solution of ammonium metalate, e.g., molybdate, and a second ammonium compound, e.g., ammonium chloride, said second ammonium compound providing additional anion for balancing the change of said cation in the solution.

Abstract: 1. IN THE PROCESS OF CARRYING OUT AMMOXIDATIONREACTIONS IN A MOVING BED REACTOR USING V2O4 AS CATALYST AND WITHOUT ADDED OXYGEN, THE IMPROVEMENT WHICH COMPRISES: (A) SEPARATING SPENT CATALYST CONSISTING ESSENTIALLY OF V2O3 FROM AMMOXIDATION PRODUCTS AND UNCREATED STARTING MATERIALS, (B) OXIDIZING A PORTION OFF SAID V2O3 TO V2O5, (C) MIXING SAID V2O5 WITH REMAINING V2O3, (D) HEATING SAID MIXTURE TO A TEMPERATURE BETWEEN ABOUT 350* AND 500* C. WHEREBY V2O4 IS FORMED, AND (E) FEEDING SAID V2O4 TO SAID AMMOXIDATION PROCESS FOR USE AS CATALYST.
