Abstract
The present invention relates to a zeolite adsorbent having an external surface area of between 20 m2·g−1 and 70 m2·g−1, a mesopore volume (Vmeso) of less than or equal to 0.20 cm3·g−1, and a content of non-zeolite phase (NZP) of less than or equal to 6%, and in which at least one of its dimensions is greater than or equal to 30 μm.The invention also relates to the process for preparing said zeolite materials in agglomerated form and to the uses thereof for gas-phase or liquid-phase separation operations.
