A pressure of about 250 atmospheres is commonly employed. The process is of immense importance for the fixation of nitrogen for fertilizers. It was developed in 1908 by Fritz Haber and was developed for industrial use by Carl Bosch (1874–1940), hence the alternative name Haber-Bosch process. The nitrogen is obtained from liquid air.
The production of ammonia (NH 3) from nitrogen (N 2) and hydrogen (H 2) gases occurs according to the Haber–Bosh process ( Eq. 11.vii ). This is a high-pressure, high-temperature chemical reaction that requires fine particulates of modified iron oxide as a catalyst. N 2 and H 2 are passed over the catalyst and NH 3 is subsequently formed.
The Haber-Bosch Process for Synthesis of Ammonia. An example of an industrial catalytic process is the Haber-Bosch process. Karl Bosch (1874–1940) was a German chemical engineer who was responsible for designing the process that took advantage of Fritz Haber's discoveries regarding the N 2 + H 2 /NH 3 equilibrium to make ammonia …
