Birkeland–Eyde process - Wikipedia

The Birkeland–Eyde process was one of the competing industrial processes in the beginning of nitrogen based fertilizer production. It was developed by Norwegian industrialist and scientist Kristian Birkeland along with his business partner Sam Eyde in 1903, based on a method used by Henry Cavendish in 1784.

Ammonia - The Essential Chemical Industry

The manufacture of ammonia is crucial for the world's agricultural industry for from it all fertilizers that contain nitrogen are produced. Uses of ammonia. The manufacture of fertilizers is by far the most important use of ammonia. These include urea, ammonium salts (ammonium phosphates, ammonium nitrate, calcium.

Nitric acid - The Essential Chemical Industry

Nitric acid is manufactured from ammonia and is a key chemical in the manufacture of fertilizers. Uses of nitric acid. By far the principal use of nitric acid (80%) is in the manufacture of fertilizers. Of this 96% is used . This part of the process involves the oxidation of ammonia to nitrogen monoxide (nitric oxide):. The conditions.

A model based on equations of kinetics to study nitrogen dioxide .

Oct 8, 2015 . Atomic oxygen is a vital particle in the dissociation of nitrogen dioxide inside the plasma reactor. According to Table 1, the production of NO, NO−2 and O2 is based on dissociation of NO2 in the reactor. Moreover, the formation of NO2 also occurs along three possible routes. In the first route, electron is.
