<p>The invention relates to a method for purifying a supply gaseous flow containing at least 5 vol. % of N<SUB>2</SUB>O 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 N<SUB>2</SUB>O 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 N<SUB>2</SUB>O from said flow and to produce a purified gaseous flow; and (b) recovering a purified gaseous flow having an N<SUB>2</SUB>O content lower than the N<SUB>2</SUB>O content of the supply gaseous flow contacted with the main adsorbent during step (a).</p> |
