Petroleum Coke Manufacturers

Petroleum coke is a black or dark gray hard solid petroleum product with metallic luster, porous, and formed by tiny graphite crystals in the form of granular, columnar or needle-like carbon bodies. Petroleum coke composition is hydrocarbon, containing 90-97% carbon and 1.5-8% hydrogen, and also contains nitrogen, chlorine, sulfur and heavy metal compounds. It is metallic, porous, granular and columnar-needle shaped.

The main uses of petroleum coke are pre-baked anode and anode paste for electrolytic aluminum, carbonizing agent for carbon industry, graphite electrode, silicon and fuel for smelting industry, and it is a by-product of high temperature cracking of raw oil in delayed coking unit to produce light oil. The yield of petroleum coke is about 25-30% of that of crude oil. Its low calorific value is about 1.5-2 times that of coal, ash is not more than 0.5%, volatile matter is about 11%, and its quality is close to that of anthracite.
