  • The synthesis of Ammonia had long been perceived to be the holy grail of chemistry
  • Fritz Haber first developed the process during the summer of 1904
  • Haber’s process was then further developed by Carl Bosch
  • In 1910, Bosh secured patent, which confirmed that the synthesis of ammonia was possible
  • The Haber-Bosch method utilizes a high temperature and elevated pressure, a metal catalyst, and gas circulation to synthesize ammonia
  • The pressure needs to be between 200 and 400 atmospheres while the temperature needs to be between 400 and 650 degrees Celsius.
  • The efficiency of the process is a function of the pressure and temperature: the highest yields are produced at higher pressures and lower temperatures.
  • With the development of the Haber-Bosch Process, the mass manufacturing of ammonia began
