The Haber–Bosch process is one of the largest contributors to a buildup of reactive nitrogen in the biosphere, causing an anthropogenic disruption to the nitrogen cycle. Since nitrogen use efficiency is typically less than 50%, farm runoff from heavy use of fixed industrial nitrogen disrupts biological habitats. See more The Haber process, also called the Haber–Bosch process, is the main industrial procedure for the production of ammonia. It is named after its inventors, the German chemists Fritz Haber and Carl Bosch, … See more Most ammonia is produced by the Haber process, emitting two tons of .CO 2/ton of ammonia. Steam reforming produces hydrogen from hydrocarbons. The hydrogen is then … See more Synthesis parameters The reaction is: The reaction is an exothermic equilibrium reaction in which the … See more When first invented, the Haber process competed against another industrial process, the cyanamide process.
