Petroleum Coke

Petroleum coke is a carbonaceous product obtained in the oil refining process. It is abbreviated as Coke or Petcoke, and is a carbon-rich solid material derived from final cracking process — a thermo-based chemical engineering process that splits long chain hydrocarbons of petroleum into shorter chains— that takes place in coker units. There are two distinctive grades of Petroleum Coke viz. Calcinable or Green Petcoke and Fuel Grade Petcoke..


Calcinable grade coke or Green Petcoke, also referred as RPC is produced at Koyali, Barauni, Bongaigaon, Digboi and Guwahati refineries of IndianOil.
Fuel Grade Petcoke is produced at Panipat, Paradip, Koyali and Haldia refineries of IndianOil.
