Haber's process is used for the industrial production of ammonia. The process conditions at which maximum yield can be obtained, include 15-20mPa pressure, 400-500 degrees Celsius of the temperature, use of methane as a source of hydrogen, use of iron-based catalysts and combined with K2O, CaO, SiO2, and Al2O3<span>. Reuse of unreacted gases can lead to the achievement of 97% yield. </span>
