Hengyuan Carbon Materials Co.,Ltd., with a registered capital of 1.05 billion yuan and covering an area of 195 acres, has built 12 main and auxiliary units including a 550,000-ton/year slurry extraction unit, a 400,000-ton/year rich aromatic oil hydrotreating unit, an 180,000-ton/year needle coke unit, a 150,000-ton/year green coke calcination unit, as well as 18 public and auxiliary system units. It possesses the largest single-unit needle coke production facility in China. The company adopts the internationally advanced needle coke coking patented technology X-Coker™ and the "Two Furnaces Three Towers" process. Its products include needle coke (calcined coke), lithium-ion battery anode materials, pitch, rubber plasticizer, industrial white oil, LPG, sulfur, and over ten other products.

The high-end carbon materials industrial park project,with an investment of 4.098 billion yuan, started in February 2022 and officially commenced trial operation in December 2023, producing the first tower of oil-based needle coke. After strict inspection, the product fully met the design specifications. The needle coke product features high true density, low thermal expansion coefficient, low sulfur and nitrogen content, low volatile and ash content, and stable resistivity, fully meeting the indicator requirements for producing ultra-high power graphite electrodes.
