Ammonia Synthesis: Commercial Practice, tons per year and virtually all of this ammonia is produced from a mixture of hydrogen and nitrogen over a promoted iron catalyst operating at elevated temperature and pressure. Over 90% of ammonia produced is used as a fertilizer, principally in the form of urea or ammonium nitrate.

Alternative Noniron Catalysts,pressures (typically in excess of 130 Bar), high temperatures (up to 823 K), and very large catalyst volumes (in excess of 60 m.) to achieve good process economics, although pressures down to around 80 bar are used in the most recent processes.
