Method for removing N
22222The invention relates to a method for purifying a supply gaseous flow containing at least 5 vol. % of NO and oxygen, in which: (a) the gaseous flow is contacted with a main adsorbent (3) including at least one zeolite exchanged at more than 50% by one or more metal cations and having an NO adso...

| Summary: | 22222The invention relates to a method for purifying a supply gaseous flow containing at least 5 vol. % of NO and oxygen, in which: (a) the gaseous flow is contacted with a main adsorbent (3) including at least one zeolite exchanged at more than 50% by one or more metal cations and having an NO adsorption capacity, as measured under 1 bar and at 200° C., of more than 80 Ncm/g in order to adsorb at least a portion of the NO from said flow and to produce a purified gaseous flow; and (b) recovering a purified gaseous flow having an NO content lower than the NO content of the supply gaseous flow contacted with the main adsorbent during step (a). |
