Petroleum coke is a product obtained by distilling crude oil and separating light and heavy oils, and then obtaining heavy oils by thermal cracking. Petroleum coke can be used in graphite, smelting and chemical industries depending on its quality.

From the appearance point of view, the coke is irregularly shaped, black lumps or particles of different sizes, with metallic luster, the particles of the coke have a porous structure, and the main elemental composition is carbon.

Chemical properties of coke

Petroleum coke has its unique physical, chemical and mechanical properties. It is itself a non-volatile carbon with heat generating parts, volatiles and mineral impurities, that is, sulfur, metal compounds, water, ash and other substances contained. These indicators determine The chemical properties of coke.

The role of petroleum coke

Petroleum coke has a wide range of functions. Low-sulfur, high-quality cooked coke, such as needle coke, is mainly used to manufacture ultra-high-power graphite electrodes and certain special carbon products. In the steelmaking industry, needle coke is still developing electric furnace steelmaking Important material for new technologies.

Generally speaking, medium sulfur and ordinary cooked coke are used in large amounts for aluminum smelting, while high sulfur and ordinary green coke are used in chemical production, such as manufacturing calcium carbide, silicon carbide, etc. Of course, they are also used as metals Fuel for casting.
