Haber Process for the Production of Ammonia

a catalyst (a porous iron catalyst prepared by reducing magnetite, Fe 3 O 4). Osmium is a much better catalyst for the reaction but is very expensive. This process produces an ammonia, NH 3 (g), yield of approximately 10-20%. The Haber synthesis was developed into an industrial process by Carl Bosch.

Haber-Bosch Process - an overview | ScienceDirect Topics

The Haber-Bosch process was one of the most successful and well-studied reactions, and is named after Fritz Haber (1868–1934) and Carl Bosch (1874–1940). Haber first proposed the use of a high-pressure reaction technique. Furthermore, in order to overcome the low conversion-per-pass of ammonia, he introduced an important concept: the ...

Overview. The Haber process, also called the Haber–Bosch process, is the reaction of nitrogen and hydrogen, over an iron substrate, to produce ammonia. The Haber process is important because ammonia is difficult to produce on an industrial scale.

The catalyst used in the Haber process is magnetite (Fe 3 O 4) fused with smaller amounts of promoters consisting of other metal oxides. The catalyst is ground finely such that it has a large surface area of about 50 m 2 g-1, and the magnetite is reduced to iron. The large surface area allows gaseous molecules to rapidly absorb and react.
