  • Ammonia Synthesis for Fertilizer Production

    Ammonia Synthesis for Fertilizer Production

    synthesis is the Haber-Bosch process, created by Fritz Haber in 1905 and developed for industry by Carl Bosch in 1910. The overall process synthesizes ammonia from molecular nitrogen and hydrogen by feeding the reactants over iron catalysts at a high pressure and temperature, requiring bulky, well-insulated reactors to house the process.

    The Haber–Bosch process is used industrially to fix atmospheric nitrogen to produce 160 million tonnes of ammonia per year. Most of this ammonia is then converted in to ammonium sulfate for fertilisers. The synthesis of the ammonia uses an iron catalyst and requires high temperatures (400–600°C) and high pressures (20–40MPa).
