| 摘要 |
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 m2 ⋅ g-1, 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 cm3 ⋅ g-1 and 0.18 cm3 ⋅ g-1, a (Vmicro - Vmeso)/Vmicro ratio of between -0.3 and 1.0, non-inclusive, and a non-zeolite phase (PNZ) content such that 0 < PNZ ≤ 30%. |
