4. Modern Ammonia Production (The Haber Process) Achieved by the direct combination of hydrogen and nitrogen, over an iron or aluminium catalyst. Hydrogen is obtained from the decomposition of methane by heating. Nitrogen is obtained from the distillation of liquefied air. The reaction is shown below: N 2 (g) + 3H 2 (g) ⇌ 2NH 3 (g)
