What is the Haber process used for?<\/strong><\/h2>\n

 <\/p>\n

Manufacture of ammonia in industry<\/strong><\/h2>\n
    \n
  1. Most of the world supply of ammonia is manufactured through Haber process<\/strong>.<\/li>\n
  2. The raw materials<\/strong> for the manufacture of ammonia are hydrogen gas<\/strong> and nitrogen gas<\/strong>. The ratio for the raw materials is one portion of nitrogen to three portions of hydrogen.
    \n(a) Nitrogen is obtained from the fractional distillation of liquid air.
    \n(b) Hydrogen can be obtained by two methods: The reaction between methane (from natural gas) or heated coke with steam.
    \n\"What<\/li>\n
  3. The optimum conditions for Haber process is
    \n(a) Temperature: 450\u00b0C
    \n(b) Pressure: 200 atmosphere
    \n(c) Catalyst: red hot iron<\/li>\n
  4. During Haber process:
    \n(a) A mixture of one volume of dry nitrogen gas and three volume of pure hydrogen gas are mixed and passed to the compressor and compressed to a pressure of about 200 atm.
    \n(b) The mixture is then passed through layers of heated and finely divided iron catalyst<\/strong> in the reactor at a temperature of about 450\u00b0C.
    \n(c) Ammonia is produced in the reactor but the reaction is reversible.
    \n\"What
    \n(d) The production of ammonia is exothermic<\/strong> and gives out heat. It is passed into the cooling chamber, then liquefied and separated to get a better yield.
    \n(e) The unreacted nitrogen and hydrogen are\u00a0recycled and passed back into the reactor converted into ammonia,
    \ntogether with the new source of nitrogen and hydrogen.<\/li>\n
  5. About 98% of nitrogen and hydrogen are converted into ammonia.<\/li>\n<\/ol>\n
