Question

Petroleum coke or petcoke, is a final carbon-rich solid material that derives from oil refining.
It is categorized as a “bottom of the barrel” fuel as it is essentially residual waste material which is obtained after refining coal to extract lighter fuels like petrol.
Petcoke is abundantly used in India in several manufacturing industries such as cement, steel and textile and it is generated in vast quantities by refineries as it is significantly cheaper that coal, has high calorific value and is easier to transport and store.
It has high carbon content and when it does combust it releases up to 10% more CO2 per unit of energy that normal coal.
