Overview:
Recently, the Union government of India permitted the import of pet coke for making graphite anode material for lithium-ion batteries.
About Petroleum Coke:
- It 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.
- Application:
- It is widely used by power stations and several manufacturing industries including cement, steel and textile plants in India.

Q1) What is Bitumen?
Bitumen is a sticky, black, and highly viscous liquid or semi-solid form of petroleum. It is a naturally occurring substance that is often found in oil sands and asphalt deposits.
