Linhuan Coking Co., Ltd. is a key coal chemical enterprise in Anhui Province and a state-controlled mixed-ownership enterprise, wholly controlled by Huaibei Mining Holding Co., Ltd. (A-share stock code: 600985). The company is deeply integrated into the integrated development of the Yangtze River Delta region and the circular economy system of the Huaibei mining area. Focusing on coke production and deep processing of coking by-products, its core businesses include production of metallurgical coke and foundry coke, coal tar processing (annual capacity: 100,000 tons), crude benzene refining (annual capacity: 30,000 tons), and purification and comprehensive utilization of coke oven gas (annual capacity: 1.2 billion cubic meters). Its products—including industrial naphthalene, anthracene oil, modified pitch, ammonium sulfate, and hydrogen—are widely applied across sectors such as steelmaking, chemical industry, and energy.  

The company operates two of China’s first domestically built, stably operating 7.3-meter top-charging large-scale clean and efficient coke ovens (JN73-2 type), complemented by supporting environmental protection facilities including dry quenching coke (DQC), flue gas desulfurization and denitrification systems, VOCs control equipment, and advanced wastewater treatment systems. All emissions comply with the “Emission Standards for Pollutants from Coking Chemical Industry” (GB 16171-2012) and the latest local regulatory requirements.  

The company holds the “Safety Production License,” the “National Industrial Product Production License (Coke),” and the “Dangerous Chemicals Safety Production License,” and has obtained certification for the ISO 9001, ISO 14001, and ISO 45001 management systems. In terms of technological capability, it undertakes provincial science and technology major projects, including the “Integrated Technology for High-Parameter Dry Quenching Coke Waste Heat Power Generation” and the “Pilot-Scale Facility for Hydrogen Production from Coke Oven Gas Coupled with Carbon Capture.” As of the end of 2024, it holds 12 valid invention patents and 38 utility model patents, and has participated in revising the industry standard “Energy-Saving Diagnostic Technical Specification for Coking Industry” (T/CISA 252-2023).  

Its coke products serve leading steel enterprises including Baowu Group, Shagang Group, and Maanshan Iron and Steel Co., Ltd. Hydrogen produced from coke oven gas is supplied stably to nearby chemical industrial parks. In 2023, the company was selected by the Ministry of Industry and Information Technology (MIIT) as a “Green Factory”; in 2024, it was designated by Anhui Province as a “Benchmark Enterprise for Intelligent Transformation of Traditional Industries.” Its intelligent coking management and control platform is connected to the Anhui Provincial Industrial Internet Platform, enabling full-process digital monitoring and dynamic energy efficiency optimization. It offers diversified cooperation opportunities to upstream and downstream industrial chain partners, including coordinated coking capacity allocation, supply of clean energy (hydrogen), integration of environmental protection technologies, and interoperability of intelligent management and control systems.
