The Petroleum coke is a solid, carbon-rich byproduct obtained during the refining of heavy petroleum fractions. It is generated in coker units where residual oils are thermally cracked, leaving behind a dense, high-energy material. Petcoke is widely used as a fuel in power generation, cement manufacturing, and industrial boilers due to its high calorific value. It is also a critical raw material in metallurgical processes, particularly for producing calcined coke, which is used in aluminum anodes, steel electrodes, and other carbon products. The quality of petroleum coke, including sulfur, ash, and volatile matter, varies based on crude oil type and refining process, influencing its industrial use and environmental impact. Fuel-grade petcoke is consumed for energy, while calcined coke undergoes heat treatment to remove impurities and enhance performance in industrial applications. Despite environmental concerns regarding sulfur emissions, petroleum coke remains a cost-effective and energy-dense material. Its applications extend to chemical industries, where it is processed into carbon black, graphite, and other carbon-based products. Petroleum coke continues to be a vital link between crude oil refining and energy, metallurgical, and chemical industries.
