The Haber process proved so essential to the German war effort [5] [14] that it is considered virtually certain Germany would have been defeated in a matter of months without it. Synthetic ammonia from the Haber process was used for the production of nitric acid, a precursor to the nitrates used in explosives.
The process was first published in 1913 and was an important source of fuel for Germany during World War Two. The process was used in the US for a while after the war, but there are currently no commercial plants in the world. The Bergius process and the Haber-Bosch process were two pioneering methods of high-pressure chemistry.
Because the syngas was essentially free of impurities, two axial-flow ammonia converters were used. In early 2000 Uhde developed a process that enabled plant capacities of 3300 mtpd and more. The key innovation was a single-flow synthesis loop at medium pressure in series with a conventional high-pressure synthesis loop. [26]
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 for the same or similar conversions. [1]
Haber process – Atmospheric nitrogen (N 2) is separated, yielding ammonia (NH 3), which is used to make all synthetic fertilizer. The Haber process uses a fossil carbon source, generally natural gas , to provide the CO for the water–gas shift reaction , yielding hydrogen (H 2 ) and releasing CO 2 .
The Haber process, [146] also called the Haber–Bosch process, is the main industrial procedure for the production of ammonia. [ 147 ] [ 148 ] 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 chemical and energy industries rely heavily on heterogeneous catalysis. For example, the Haber–Bosch process uses metal-based catalysts in the synthesis of ammonia, an important component in fertilizer; 144 million tons of ammonia were produced in 2016. [5]
From 1909 until 1913 he transformed Fritz Haber's tabletop demonstration of a method to fix nitrogen using high-pressure chemistry through the Haber–Bosch process to produce synthetic nitrate, a process that has countless industrial applications for making a near-infinite variety of industrial compounds, consumer goods, and commercial ...
