Petroleum Coke | IndianOil

Petroleum Coke. Petroleum coke is a carbonaceous product obtained in the oil refining process. It is abbreviated as Coke or Petcoke, and is a carbonrich solid material derived from final cracking process — a thermobased chemical engineering process that splits long chain hydrocarbons of petroleum into shorter chains— that takes place in coker units.
