abstract |
The present invention relates to a novel method for purifying CO2-polluted gas streams, hydrocarbons and / or nitrogen oxides, in particular based on air or synthesis gas, by adsorption on a bed of agglomerated zeolite adsorbent based on LSX zeolite or on LSX and X zeolites in which at least 90% of the cationic exchangeable sites of the LSX zeolite or of the LSX / X zeolite mixture are occupied by sodium ions, and whose inert binder represents at most 5% of the weight of the adsorbent. |
