A process for producing ammonia synthesis gas in which a pressure swing adsorption unit is utilized to replace former CO2 removal, methanation, drying and purification steps. To increase the efficiency of the process, a hydrogen fuel cell is utilized to generate electricity and a high purity nitrogen purge stream for a pressure swing absorption unit. Accordingly, after reforming and high temperature catalytic shift conversion, the feed stream is divided into a first stream to feed the fuel cell and a second stream which is directly introduced to the pressure swing adsorption unit. After the first stream is reacted in the fuel cell, a nitrogen rich stream is passed to a de-oxygenation unit and then utilized as the pressure swing adsorption purge stream.
