Abstract: The present invention relates to an improved process for exchanging alkali metal or alkaline earth metal ions in zeolites for ammonium ions. For this exchange aqueous solutions of ammo nium salts for example ammonium sulfate ammonium nitrate or ammonium chloride are cur rently being used. The resulting 'ammonium zeolites' are calcined to convert them with release of ammonia to the H form of the zeolites suitable as a catalyst. It is proposed in accordance with the invention to use ammonium carbonate instead of the am monium compounds mentioned. Since excess ammonium carbonate in contrast to the nitrates sulfates or chlorides can be recycled in the form of carbon dioxide and ammonia the amount of salt which has to be discharged is lowered significantly.
