The Advanced Manufacturing Process of Graphitized Petroleum Coke

The production of Graphitized Petroleum Coke (GPC) from raw petroleum coke is a highly specialized and energy-intensive process that transforms a relatively amorphous carbon material into a highly ordered, graphitic structure. This transformation is what imbues GPC with its superior properties, making it a sought-after material by hiiliöljykoksin toimittajat for high-performance applications.

Process Flow Overview:

• Raw Material Selection: The process begins with high-quality green petroleum coke, often sourced from delayed coking units in oil refineries. The selection criteria are critical, focusing on low sulfur, low ash, and a high volatile matter content, which are precursors for good graphitization.
• Calcination: The green coke undergoes calcination in rotary kilns or shaft kilns at temperatures typically ranging from 1200°C to 1350°C. This process removes residual hydrocarbons, moisture, and volatile matter, densifying the coke and improving its electrical conductivity. The resulting material is known as Calcined Petroleum Coke (CPC).
• Crushing and Sizing: The calcined coke is then crushed and screened into various particle sizes to meet specific industrial requirements. Precision in sizing ensures optimal performance in downstream applications.
• Graphitization: This is the most critical and energy-intensive step. The sized CPC is loaded into Acheson furnaces or longitudinal graphitization furnaces. It is then heated to extremely high temperatures, ranging from 2500°C to 3000°C, in an inert atmosphere. At these temperatures, the amorphous carbon atoms rearrange into a highly ordered, layered graphitic structure. This thermal treatment reduces impurities further, particularly sulfur, and enhances the crystallinity, electrical conductivity, and thermal stability of the material.
• Cooling and Finishing: After graphitization, the material is slowly cooled under controlled conditions. Once cooled, it undergoes further crushing, screening, and, if necessary, fine grinding to achieve the desired particle size distribution for specific applications, such as recarburizers, electrodes, or friction materials.
• Quality Control and Packaging: Throughout the entire process, rigorous quality control measures are implemented. Samples are taken at each stage and tested for critical parameters such as carbon content, sulfur content, ash content, resistivity, and bulk density. Final products are then packaged according to client specifications, ready for shipment by hiiliöljykoksin viejät.

The target industries for GPC include metallurgy (steel, aluminum, ferroalloys), chemical industries (silicon carbide, titanium dioxide), and specialty carbon products (electrodes, friction materials). GPC contributes to energy saving in metallurgical processes by improving the efficiency of carbon injection and electrode performance. Its inherent corrosion resistance at high temperatures also extends the service life of refractory linings and other furnace components.

Technical Specifications of Graphitized Petroleum Coke (GPC)

The precise technical specifications of Graphitized Petroleum Coke are paramount for its effective application across various industries.
