Example: Haber-Bosch process (Ammonia Synthesis)

Haber-Bosch process developed by Fritz Haber and Carl Bosch in 1918, the process used
both high temperatures and high pressures and an iron catalyst to produce a large
amount of ammonia from gaseous hydrogen and nitrogen. Ammonia fertilizers feed the
world. Today, ammonia is the second most produced chemical by tonnage, after only
sulfuric acid
