Petroleum coke is a product obtained by separating light and heavy oil from crude oil through distillation, and then converting heavy oil through thermal cracking. From the appearance, coke appears as irregularly shaped black blocks (or particles) of varying sizes, with a metallic luster. The particles of coke have a porous structure, and the main element composition is carbon, accounting for more than 80%, with hydrogen content of 1.5% -8%, and the rest being oxygen, nitrogen, sulfur, and metal elements.
Petroleum coke can be used in industries such as graphite production, smelting, and chemical engineering based on its quality.
