Petroleum coke is widely used in the production of graphite electrodes, carbon anodes and anode paste for aluminum smelting, as well as other metallurgical applications.
Petroleum coke is a hard, black to dark-gray carbonaceous material characterized by a metallic luster and porous structure. It typically contains 90–97% carbon and 1.5–8% hydrogen, along with varying amounts of nitrogen, chlorine, sulfur, and heavy metal compounds. Calcination removes moisture and volatile matter, increases carbon content, and improves electrical conductivity and high-temperature performance.

Green petroleum coke is produced during petroleum refining and contains relatively high levels of moisture and volatile matter. Calcined petroleum coke (CPC) undergoes high-temperature calcination to reduce moisture and volatile matter, increase carbon content, and improve electrical conductivity, making it suitable for carbon and metallurgical applications.
Key specifications include sulfur content, fixed carbon, ash, volatile matter, moisture, particle size, and density. Electrical resistivity and other properties may also be relevant depending on the intended application. The appropriate grade should be selected according to the specific production process and quality requirements.
Please provide the required petroleum coke grade, chemical specifications (sulfur, fixed carbon, ash, volatile matter, etc.), particle size, quantity, delivery destination, and any specific packaging or inspection requirements.
