The patent titled “A Production Process for Improving the Properties of Needle Coke”, applied for by Jinzhou Petrochemical Research Institute, was authorized by the **Intellectual Property Office on February 6. 　　This patent addresses the key challenges in the production of needle coke, such as insufficient performance stability and difficulties in improving quality, by proposing a unique technical approach that involves optimizing the raw materials and adjusting the process control parameters. Through laboratory tests and multiple pilot-scale trials, it has been proven that this process can significantly improve the crystallinity and oxidation resistance of needle coke, effectively reduce its thermal expansion coefficient, and enhance its mechanical compressive strength. It enables stable control over the performance of needle coke products, meeting the stringent requirements of fields such as ultra-high power graphite electrodes and lithium-ion battery anodes. At present, this patented technology is ready for industrial application, which will further enhance the added value and market competitiveness of Jinzhou Petrochemical’s needle coke products.
