Features of Graphitized Petroleum Coke
High carbon
High purity 98.5-99.5%.
Low sulfur
0.01% to 0.05% low sulfur, stable distribution, can effectively reduce the adverse effect of sulfur on the alloy during the spheroidization and inoculation process, and save costs.
Low nitrogen
Nitrogen content 50 ppm~300 ppm (0.005%-0.03%).
High carbon recovery rate: 92-98%.
Fast absorption
Easy to dissolve iron.
High graphite core and a high degree of graphitization
It can reduce the shrinkage tendency of molten iron and improve the mechanical properties of castings.
Stable vaporization, good absorption rate, obvious heating effect
No slag. It can effectively protect and extend the life of the furnace and reduce the consumption of the furnace lining.
Types of Graphite Petroleum Coke
Calcined graphite petroleum coke
This type has undergone a calcination process, enhancing its electrical conductivity and thermal stability.
Green petroleum coke
This uncalcined material is rich in sulfur and volatile content, used in specific applications where lower quality is acceptable.
Low sulfur/high carbon petroleum coke
Particularly used in high-end steel production, this grade minimizes sulfur contamination, ensuring higher quality steel output.
High-temperature graphite petroleum coke
Designed for applications requiring extreme thermal resistance, this grade excels in situations demanding high durability.
Graphitized petroleum coke is widely used in industry. It is used as a recarburizer in metallurgy, casting, and precision casting; it is used to make high-temperature crucibles in smelting, lubricants in the mechanical industry, and to make electrodes and pencil cores; Graphitized petroleum coke is widely used in Advanced refractory materials and coatings in the metallurgical industry, stabilizers for pyrotechnic materials in the military industry, pencil leads in the light industry, carbon brushes in the electrical industry, electrodes in the battery industry, catalysts in the fertilizer industry, etc. Graphitized petroleum coke can be used in graphite, smelting, and chemical industries depending on its quality.
Production Process of Graphite Petroleum Coke
Petroleum coke production: Petroleum coke is a byproduct of the oil refining process. It is a carbonaceous solid derived from crude oil.High-quality raw petroleum coke with low levels of impurities is selected for further processing.
Calcination: The selected petroleum coke is subjected to a high-temperature process known as calcination. This involves heating the coke to temperatures ranging from 1200 to 1400 degrees celsius in a rotary kiln or shaft kiln.Calcination removes volatile matter and moisture from the coke, leaving behind a porous, carbon-rich material.
Crushing and sizing: The calcined coke is then crushed and screened to achieve the desired particle size. The sizing is crucial for the subsequent graphitization process.
Graphitization: The calcined coke is exposed to high temperatures (typically above 2500 degrees celsius) in the presence of a catalyst or in a specialized graphitization furnace.During this process, the carbon atoms in the coke rearrange into a crystalline structure, transforming it into graphite. The graphitization process imparts specific properties to the material, including high thermal conductivity and excellent electrical conductivity.
Purification (optional): Depending on the intended use, the graphitized petroleum coke May undergo additional purification steps to further reduce impurities.
Final processing: The final graphitized petroleum coke product is often ground into a fine powder, pelletized, or packaged in bulk depending on the requirements of end-users.
