Uses and Raw Materials.
The Haber
process is named after the German
chemist
Fritz Haber. It involves the industrial manufacture of
Ammonia from Nitrogen and Hydrogen gas.
Ammonia is used to make nitric acid,
which in turn reacts with ammonia to form ammonium nitrate.
Ammonium nitrate is a very
important fertiliser.
Raw Materials.
Nitrogen is easily obtained from air by fractional
distillation,
(Air is almost
80% nitrogen).
Hydrogen is obtained from methane (natural gas)
or naphtha.
The hydrocarbon
is reacted with steam.
methane
+ steam
carbon dioxide + hydrogen.
CH4(g) +
2H2O(g) CO2(g) + 4H2(g)
The raw
materials are therefore
air - for nitrogen,
methane and water - for hydrogen.
