    Abstract: Aspects of the present invention relate to an improved process for exchanging alkali metal or alkaline earth metal ions in zeolites for ammonium ions. For this exchange, aqueous solutions of ammonium salts, for example ammonium sulfate, ammonium nitrate or ammonium chloride, are currently 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. Certain methods provided herein use ammonium carbonate instead of the ammonium compounds mentioned. As 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.

    Abstract translation: 本发明的方面涉及用于在铵离子的沸石中交换碱金属或碱土金属离子的改进方法。 对于这种交换，目前正在使用铵盐的水溶液，例如硫酸铵，硝酸铵或氯化铵。 将所得的“铵沸石”煅烧以将其转化为氨释放到适合作为催化剂的沸石的H形式。 本文提供的某些方法使用碳酸铵代替所提及的铵化合物。 作为过量的碳酸铵，与硝酸盐相比，硫酸盐或氯化物可以以二氧化碳和氨的形式再循环，必须排出的盐的量显着降低。
