    摘要: Zeolites exchanged with lithium, rubidium, cesium cations and trivalent cations are prepared by first partially, fully or excessively ion-exchanging a sodium-containing zeolite, a potassium-containing zeolite or a sodium- and potassium-containing zeolite with trivalent cations, then calcining the partially, fully or excessively trivalent cation-exchanged zeolite, and then ion exchanging the calcined zeolite with lithium rubidium, cesium cations, thereby replacing hydrogen and any sodium and/or potassium cations remaining in the zeolite with lithium, rubidium, cesium cations, whereby trivalent cations present in the zeolite will not be substantially replaced by the lithium ions.
