ABSTRACT:
Adsorbent material well adapted for the purification of gases (notably by the PSA and TSA methods) by adsorbing impurities therefrom that are more polar or polarizable than the gases to be purified, e.g., nitrogen, the oxides of carbon and hydrocarbons, comprises a matrix of a type 5A zeolite molecular sieve and a kaolinite clay binder therefor, the clay binder having a concentration of at least 75% by dry weight of kaolinite and a maximum quartz concentration of 20% by dry weight.
