Claim 23:
24. The process of claim 16, wherein:
the ion-exchanged base metal is Cu and the Cu, calculated as CuO, is present in the zeolite in an amount of from about 0.1% to about 4.0% by weight, based on the total weight of the calcined ion-exchanged zeolite on a volatile-free basis;
the ion-exchanged palladium, calculated as elemental palladium, is present in the zeolite in an amount of from about 0.1% to about 4.0% by weight, based on the total weight of the calcined ion-exchanged zeolite on a volatile-free basis; and
at least about 50% of the Cu and at least about 50% of the palladium reside in the ion-exchange sites in the pore network of the zeolite.
