Abstract

The present invention relates to the use of an adsorbent material for the treatment of gases, said adsorbent material comprising: A) at least one zeolite chosen from LTA zeolites and FAU zeolites with an Si / Al molar ratio of between 1 and 3, limits included; B) at least one zeolite chosen from FAU zeolites with an Si / Al molar ratio of between 3 and 30, limits excluded, MFI zeolites and *BEA zeolites; and C) at least one agglomeration binder. The invention also relates to the process for treating gases using said adsorbent material.
