ハーバー・ボッシュ法
In the early decades of the 20th century, the Nobel prize-winning chemists Carl Bosch of IG Farben and Fritz Haber developed the Haber process which utilized molecular nitrogen (N2) and methane (CH4) gas in an economically sustainable synthesis of ammonia (NH3). The ammonia produced in the Haber process is the main raw material of the Ostwald process.
