Petroleum coke is a porous solid material, black or dark gray with high carbon content and different levels of sulphur, depending on its quality, which is produced as a by-product of oil refining process.
Thanks to its low volatility and its high calorific value, fuel grade petroleum coke is an excellent fuel option for electrical generation plants, cement plants and other industries who need to achieve high combustion temperatures. About 71% of the total production of petroleum coke is used as an energy source. Petroleum coke is also an excellent carbon source.
