The Haber process or Haber-Bosch process is the primary industrial method used to make ammonia or fix nitrogen. The Haber process reacts nitrogen and hydrogen gas to form ammonia: N 2 + 3 H 2 â 2 NH 3 (Î´H = â92.4 kJÂ·mol â1).
The Haber process, also called the HaberâBosch process, is an artificial nitrogen fixation process and is the main industrial procedure for the production of ammonia today.It is named after its inventors, the German chemists Fritz Haber and Carl Bosch, who developed it in the first half of the twentieth century.aber together with his assistant Robert Le Rossignol developed the high-pressure devices and catalysts used to demonstrate the Haber process at laboratory scale. They demonstrated their process in the summer of 1909 by producing ammonia from air drop by drop, at the rate of about 125 ml (4 US fl oz) per hour.
