<P>PROBLEM TO BE SOLVED: To provide a new method of purifying a gas stream contaminated by CO2, hydrocarbons and/or nitrogen oxides, in particular a gas stream based on air or a syngas, by adsorption on a bed of aggregated zeolitic adsorbent based on an LSX zeolite or LSX and X zeolites. <P>SOLUTION: At least 90% of the exchangeable cationic sites of the LSX zeolite or of the LSX/X zeolite blend are occupied by sodium ions, and the inert binder of which represents at most 5% of the weight of the adsorbent. <P>COPYRIGHT: (C)2013,JPO&INPIT |
