The current production route of nitric acid is known as "the Ostwald process" and has been used for nearly a century. A simplified scheme of a modern plant is shown in Figure 1. In this process, ammonia is combusted (oxidized) in air, to nitric oxide (NO). This highly exothermic reaction is carried out over a highly selective platinum ...

The Ostwald process is the industrial process for producing nitric acid. It was developed by Wilhelm Ostwald in 1887. The process involves the oxidation of ammonia to nitrogen dioxide, which is then absorbed in water to form nitric acid. The main advantage of the Ostwald process over other methods of nitric acid production is that it is less ...
