The Haber process, [1] also called the Haber–Bosch process, is the main industrial procedure for the production of ammonia. [ 2 ] [ 3 ] It converts atmospheric nitrogen (N 2 ) to ammonia (NH 3 ) by a reaction with hydrogen (H 2 ) using finely divided iron metal as a catalyst:
The German chemists Fritz Haber and Carl Bosch developed the process in the first decade of the 20th century, and its improved efficiency over existing methods such as the Birkeland-Eyde and Frank-Caro processes was a major advancement in the industrial production of ammonia. [8] [9] [10] The Haber process can be combined with steam reforming ...
The history of the Haber process begins with the invention of the Haber process at the dawn of the twentieth century. The process allows the economical fixation of atmospheric dinitrogen in the form of ammonia, which in turn allows for the industrial synthesis of various explosives and nitrogen fertilizers, and is probably the most important industrial process developed during the twentieth ...
Abiological nitrogen fixation describes chemical processes that fix (react with) N 2, usually with the goal of generating ammonia. The dominant technology for abiological nitrogen fixation is the Haber process, which uses iron-based heterogeneous catalysts and H 2 to convert N 2 to NH 3. This article focuses on homogeneous (soluble) catalysts ...
The Haber process, [144] also called the Haber–Bosch process, is the main industrial procedure for the production of ammonia. [145] [146] It converts atmospheric nitrogen (N 2) to ammonia (NH 3) by a reaction with hydrogen (H 2) using finely divided iron metal as a catalyst:
It fixates nitrogen, a highly energy-thirsty process, by converting it to ammonia via the Haber process, also known as the Haber–Bosch process. From ammonia, the vast majority of fertilisers are made, leading to protein formation in plants and then animals. Naturally occurring sodium nitrate or potassium nitrate are also used in fertilisers.
To further develop the process for large-scale ammonia production, Haber turned to industry. Partnering with Carl Bosch at BASF, the process was successfully scaled up to produce commercial quantities of ammonia. [17] The Haber–Bosch process was a milestone in industrial chemistry.
With the process complete he was able to synthesize large amounts of ammonia, which was available for the industrial and agricultural fields. In fact, this production has increased the agricultural yields throughout the world. [5] This work won him the Nobel prize for Chemistry in 1931. [2] After World War I Bosch extended high-pressure ...
