Ammonia synthesis is the largest process in chemical industries. It was first operated at BASF one hundred years ago based on the fundamental work of Fritz Haber[1] and process engineering by Carl Bosch. Haber combined feed gas recycling with application of high pressure and an effective catalyst, e.g. Osmium, to achieve
Haber process
The Haber process can be combined with steam reforming to produce ammonia with just three chemical inputs: water, natural gas, and atmospheric nitrogen. Both Haber and Bosch were eventually awarded the Nobel Prize in Chemistry: Haber in 1918 for ammonia synthesis specifically, and Bosch in 1931 for related contributions to high-pressure chemistry.
