Abstract
Method and system on board an aircraft for the production of an oxygen-enriched gas stream from an oxygen/nitrogen gas mixture, particularly air, comprising at least one adsorber containing at least one adsorbent for adsorbing at least some of the nitrogen molecules contained in the oxygen/nitrogen feed mixture, characterized in that the adsorbent comprises a faujasite-type zeolite, having a Si/Al ratio of 1 to 1.50, exchanged to at least 80% with lithium cations. Aircraft equipped with such a system, in particular an airliner, especially an airliner of the long-range, large-capacity type.
