A two bed pressure swing adsorption process is disclosed having high yield and high production rate. The process utilizes fine or normal size zeolite sieve material and relatively short cycle times. A power saving can be obtained by sequencing the various steps of the process to provide substantially continuous use of a vacuum pump.
