The Ostwald process is a chemical process used for making nitric acid (HNO 3). [1] The Ostwald process is a mainstay of the modern chemical industry , and it provides the main raw material for the most common type of fertilizer production. [ 2 ]
Ostwald invented a process for the inexpensive manufacture of nitric acid by oxidation of ammonia. He was awarded patents for this process. [ 14 ] Ostwald's patent made use of a catalyst and described conditions under which the yield of nitric acid was near the theoretical limit .
Nitric acid is an inorganic compound with the formula H N O 3. It is a highly corrosive mineral acid. [6] ... Industrial nitric acid production uses the Ostwald process.
The Ostwald process is a chemical process for production of nitric acid (HNO 3), which was developed by Wilhelm Ostwald (patented 1902). It is a mainstay of the modern chemical industry and provides the raw material for the most common type of fertilizer production, globally (for example, ammonium nitrate , a common fertilizer, is made by ...
The nitric acid process produces nitric acid for use in making ammonium nitrate fertiliser. Using the Ostwald process, ammonia is vaporised and then oxidised over a 95% platinum and 5% rhodium catalyst at 930 °C (1,710 °F) and 6.5 bar (650 kPa) to form nitric oxide and superheated steam. The reaction gases are cooled to 38 °C (100 °F ...
Ammonia is also used for the production of plastics, fibres, explosives, nitric acid (via the Ostwald process), and intermediates for dyes and pharmaceuticals. The industry contributes 1% to 2% of global CO 2. [2] Between 18–20 Mt of the gas is transported globally each year. [3]
