China Energy Mengxi Coal Chemical Industry Co., Ltd. (formerly known as Inner Mongolia Mengxi High-Tech Group Co., Ltd.) is a large-scale energy and chemical enterprise controlled by China Energy Investment Corporation, headquartered in Ordos City, Inner Mongolia Autonomous Region. The company serves as the core platform for China Energy Investment Corporation’s coal chemical business segment and constitutes a vital supporting force for the modern energy economy of the Mengxi region. Focusing on clean and efficient coal conversion and modern coal chemical industries, the company’s core businesses encompass research, production, and sales of bulk chemical products—including coal-to-olefins, ethylene glycol, methanol, polyethylene, polypropylene, and synthetic ammonia—whose applications span plastics, chemical fibers, solvents, fertilizers, and other sectors. Leveraging high-quality coal resources in Ordos and the integrated advantages of coal, power, chemicals, and transportation offered by China Energy Investment Corporation, the company has constructed and operates major infrastructure projects at its Mengxi Base, including an annual 1.2-million-ton coal-to-olefins facility, a 600,000-ton ethylene glycol plant, supporting coal mines, a captive power plant, and a dedicated railway line. These projects constitute a key national demonstration initiative for green, low-carbon technology industrialization under the State Council’s “Innovation and Development Layout Plan for the Modern Coal Chemical Industry.” The company holds certifications including the “Safety Production Permit for Hazardous Chemicals,” “Pollutant Discharge Permit,” “Water Withdrawal Permit,” and management system certifications ISO 9001, ISO 14001, and ISO 45001. It has participated in formulating two national standards, including GB 30254–2023, and holds 17 authorized invention patents, such as the “Process for Hierarchical and Graded Utilization of Low-Rank Coal.” Additionally, it has established a pilot-scale CO₂ capture, utilization, and storage (CCUS) facility for high-concentration CO₂ capture and enhanced oil recovery with geological sequestration. In 2024, its industrial output value reached RMB 18.64 billion; its comprehensive olefin yield stood at 82.6%; and its methanol consumption per ton of olefins was 2.83 tons. Its key operational indicators rank among the top domestically for similar facilities. Its business covers North China and Northwest China regions, with major customers including Sinopec, CNPC, Hengli Petrochemical, and Zhejiang Satellite Petrochemical—leading downstream enterprises—and it collaborates with upstream and downstream industrial chain partners to supply high-quality chemical feedstocks, technical synergy, and green, low-carbon solutions.
