Petroleum coke, abbreviated coke, pet coke or petcoke, is a final carbon-rich solid material that derives from oil refining. Petroleum coke is a solid by-product of petroleum refining and is used in the production of carbon electrodes for the aluminum industry, graphite electrodes for steel making, as fuel in power generation, and as fuel for cement kilns. Petcoke is hydrophobic as compared to coal which is hydrophilic, thereby having edge during rainy season. Being solid fuel, Petcoke has low volatile matter thus no evaporation losses. Helps saving in transportation cost due to higher density compared to liquid fuels. Low ash content.  Ask for low sulphur content of less than 2%.
