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.
