Abstract: A pressure swing adsorption process is provided to remove oxygen from a hydrogen stream through the use of a copper material in combination with layers of adsorbent to remove water, C2 and C3 hydrocarbons, as well as other impurities. The feed gas comprises more than 70 mol % hydrogen, at least 1 mol % methane and more than 10 ppmv oxygen. The purified product hydrogen stream comprises greater than 99 mol % hydrogen, with less than 1 ppmv oxygen.
