ABSTRACT:
Zeolite adsorbent, and method of production, exchanged with calcium and barium cations, for purifying or separating a gas or gas mixture, in particular air, so as to remove therefrom the impurities found therein, such as hydrocarbons and nitrogen oxides (NxOy). The adsorbent is preferably an X or LSX zeolite and the gas purification process is of the TSA type.
