Hengyuan Carbon Materials Co.,Ltd. was established in 2021 with a registered capital of 1.05 billion yuan and covers an area of 195 acres.

The company has built 12 main and auxiliary units including a 550,000-ton/year slurry de-solidification unit,a 550,000-ton/year supercritical extraction unit, a 400,000-ton/year rich aromatic oil hydrotreating unit, a 200,000-ton/year special oil hydrogenation 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.

Positioned for the comprehensive development of oil-based carbon materials,it focuses on extending towards high-end carbon materials and the carbon material industry chain, producing high-precision products such as ultra-high power graphite electrodes, power battery anode materials, graphite products, pitch-based carbon fiber, mesophase pitch, isostatic graphite, impregnating pitch, coating pitch, carbon black, white carbon black, and carbon fiber felt.

The company also established the High-end Carbon Materials Research Institute.This project started in February 2022 with an investment of 4.098 billion yuan 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, high particle strength, 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.

The company also collaborates with renowned domestic universities,focusing on R&D for subsequent development and application of multiple technologies such as silicon-carbon composite lithium battery anode materials, gel pitch, and third-generation semiconductors. Currently, the company has been granted over 20 invention and utility model patents, including "A Production Method for Needle Coke" and "A Nitrogen-Doped Lithium-Ion Battery Carbon-Silicon Anode Material and Its Preparation Method."
