Abstract
Methods of supplying an oxygen rich mixture to the occupants of an aircraft. The mixture is produced through a pressure swing adsorption system which has both an adsorption/production phase and a desorption/regeneration phase. The duration of one cycle of the adsorption system is less than ten seconds. The system makes use of a high-performance adsorbent which has a particle size of less than about 0.8 mm. The feed air which is introduced to the system has an inlet temperature between 50° C. and 90° C.
