The Haber process, also called the Haber–Bosch process, is the nitrogen fixation reaction of nitrogen gas and hydrogen gas, over an enriched iron or ruthenium catalyst, which is used to industrially produce ammonia. [1] [2] [3] [4]Despite the fact that 78.1% of the air we breathe is nitrogen, the gas is relatively unavailable because it is so unreactive: nitrogen molecules are …

The Haber process, also called the Haber–Bosch process, is an artificial nitrogen fixation process and is the main industrial procedure for the production of ammonia today. [2] [3] It is named after its inventors, the German chemists Fritz Haber and Carl Bosch, who developed it in the first decade of the 20th century.

Haber-Bosch process catalysts Invented in 1909 by Fritz Haber (1868-1934), the Haber-Bosch process requires very high pressure (250 atmospheres) and a temperature of approximately 932°F (500°C). The reaction also requires a porous iron catalyst. Industrially, ammonia has been produced from dinitrogen and dihydrogen by the Haber-Bosch process, which operates at …

The Haber Bosch process is over 100 years old and is expensive in energy consumption but no industrial-scale alternative exists and so it remains in use today. High emissions of the potent greenhouse gas, carbon dioxide, provide strong impetus for modern research effort into other processes which may use sources of green electricity.

The original Haber–Bosch reaction chambers used osmium as catalysts. However, under Bosch's direction in 1909, the BASF researcher Alwin Mittasch discovered a much less expensive iron-based catalyst, which is still used today. Part of the industrial production utilizes ruthenium rather than an iron-based catalysts (the KAAP process).
