Carl Bosch – developer of HaberBosch process
Haber Bosch process. Haber Bosch process is an artificial nitrogen fixation process and is the main industrial procedure for the production of ammonia. The process converts atmospheric nitrogen (N2) to ammonia (NH3) by a reaction with hydrogen (H2) using a metal catalyst under high temperatures and pressures....
Catalysis in industry The Essential Chemical .
When iron is used as the catalyst in the Haber Process, aluminium oxide is added and acts as a barrier to the fusion of the metal particles. A second promoter is added, potassium oxide, that appears to cause the nitrogen atoms to be chemisorbed more readily, thus accelerating the slowest step in the reaction scheme....
