Abstract (en)

[origin: FR2789914A1] The adsorbent contains a small proportion of an inert binder and has cationic sites occupied by barium ions alone or barium and potassium ions. The zeolitization of the binder improves the adsorbency of the product. The agglomerated zeolite adsorbent comprises at least 90% of a zeolite X with a Si/Al ratio greater than 1.15 and less than or equal to 1.5. At least 90% of the cationic exchangeable sites are occupied either by Ba ions only or Ba and K ions. The sites occupied by K ions may represent up to 1/3 of the Ba + K sites (the possible complement being made up by alkali or alkaline earth ions other than Ba). The content of inert binder is no more than 10%. Independent claims are also included for the preparation of the adsorbent and its uses as an adsorbent or separating agent.
