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.


Fuel: About 80 percent of worldwide petcoke production is “fuel-grade” petcoke (green coke), used for electricity generation and in cement kilns.

Paint and Colorings: Calcined petcoke is used in the production of titanium dioxide (TiO2), a mineral that is used as a substitute for lead in paint. TiO2 is also used as a pigment in sunscreen, plastic and food coloring.

Brick and Glass: Calcined petcoke is used by brick and glass manufacturers because it has a significantly lower ash content compared to other fuels.
