Haber process

Haber process

  • Condition
    • 450℃
    • 250 ATM
    • Iron as catalyst
  • Sources of nitrogen
    • Fractional distillation of liquid air
  • Sources of hydrogen
    • Cracking of petroleum

Contact process

  • 2 SO2(g) + O2(g) ⇌ 2 SO3(g)
    • Condition
      • 450℃
      • 1 - 2 ATM
      • Vanadium(V) oxide as catalyst
  • H2SO4 (l) + SO3 (g) → H2S2O7 (l)
    • Produce oleum
  • H2S2O7 (l) + H2O (l) → 2 H2SO4 (l)
    • Add water into oleum to form dilute sulphuric acid
