Abstract
Zeolites in particulate form that are uniformly exchanged with both lithium ions and trivalent cations are produced by first partially ion-exchanging the zeolite in powdered form with one or more selected trivalent ions, then agglomerating and calcining the partially trivalent cation-exchanged zeolite, then ion-exchanging the calcined agglomerate with lithium ions, and finally activating the trivalent cation- and lithium ion-exchanged zeolite.
