Haber process
The Haber process is a high-temperasture high-pressure process for combining nitrogen and hydrogen gasses into ammonia. The reaction is relatively inefficient, with ~5% yield per iteration.
- {{#Chem: N2 + 3H2 { Fe = 20MPa, 500-600°C } 2NH3}}
The gasses are refrigerated, the ammonia removed as a liquid, and the process is repeated. Iron oxide can be used in place of iron, because it will be rapidly reduced by the hydrogen gas to water and pure iron.
Hazards
- At the extremely high temperatures and pressures involved, rupture and explosion of the reaction vessel is a serious concern.
