Abstract
The present invention concerns the use, for gas separation and/or gas drying, of at least one zeolite adsorbent material comprising at least one type A zeolite, said adsorbent having an external surface area greater than 20 m·g, a non-zeolite phase (PNZ) content such that 0<PNZ≤30%, and an Si/Al atomic ratio of between 1.0 and 2.0. The invention also concerns a zeolite adsorbent material having an Si/Al ratio of between 1.0 and 2.0, a mesoporous volume of between 0.07 cm·gand 0.18 cm·g, a (Vmicro−Vmeso)/Vmicro ratio of between −3 and 1.0, non-inclusive, and a non-zeolite phase (PNZ) content such that 0<PNZ≤30%.
