The Haber process was essentially a laboratory process, but with the help of the industrial chemist Carl Bosch commercial production of ammonia by the Haber–Bosch process began in 1913. Haber also worked, during World War I, on the development of poison gas for military use.
Haber won the Nobel Prize in Chemistry in 1918 for "the synthesis of ammonia from its elements". Many scientists protested the award because of Haber's role in promoting the use of poison gas in war. Gold from the Sea After the war, Haber resumed his chemical research. One major project that he undertook was extracting gold from the oceans.
NH3 is manufactured by Haber's process. In this process, pure nitrogen and hydrogen gases react in the ratio of 1:3 by volume in 400°C500°C temperature, 200900 atm pressure in presence of iron as catalyst molybdenum as promoter.
This process is energyintensive (> 600 kJ mol1 ammonia), requiring high operating temperatures and pressures (150–350 atm, 350–550 °C). In the HaberBosch process, all of the hydrogen gas is produced by the steam reformation of natural gas (CH 4 + 2H 2 O→4H 2 + CO 2).
