Petroleum Coke : For Lithium-Ion Batteries

The Union government of India permitted the import of pet coke for making graphite anode material for lithium-ion batteries.

  • Petroleum Coke is a final carbon-rich solid material and residual waste material extracted from oil refining.
  • It is a spongy, solid residue from oil distillation that can be burned for fuel similar to coal.
  • It is a byproduct created when bitumen is found in tar sands.
  • Bitumen contains a higher number of carbon atoms than regular oil and it’s these atoms, extracted from large hydrocarbon molecules using heat, that go on to form petcoke.
  • It is high in calorific value and easy to transport and store.
  • It releases toxic gases like carbon dioxide, nitrous oxide, mercury, arsenic, chromium, nickel, and hydrogen chloride after burning.
  • There are two distinctive grades of Petroleum Coke viz. Calcinable or Green Petcoke and Fuel Grade Petcoke.
  • It is widely used by power stations and several manufacturing industries including cement, steel and textile plants in India.
