Abstract:China is the world′s largest producer of steel and chemicals, the production of which heavilyrelies on coal resources. Although China′s steel industry has made considerable progress in reducingenergy consumption, the total annual energy consumption continues to rise due to the industrial scaleand increased production capacities. The "Carbon Peak and Carbon Neutrality" initiative has acceleratedChina′s energy revolution, driving the development of emerging energy sources and the construction ofa modern energy system. Due to limitations in energy resources, it is difficult for China′s steel industryEnergy Environmental Protectionto adopt electric arc furnaces (EAFs) on a large scale in the short term. The traditional blastfurnace/basic oxygen furnace (BF-BOF) integrated steelmaking route is characterized by a high-carbonenergy structure, a significant crude steel output, and complex carbon emission mechanisms. Thisprocess also produces steel mill gases, primarily composed of coke oven gas (COG), blast furnace gas(BFG), and Linz-Donawitz gas (LDG). Currently, steel mill gases are primarily used as fuels, a practicewith relatively low energy conversion efficiency. However, the hydrogen, carbon monoxide, carbondioxide, and methane within these gases represent valuable sources for chemical production. Throughcontinuous technological advancements in recovering surplus steel mill gases for use in chemicalmanufacturing, the steel and chemical industries can collaborate to achieve energy conservation,emission reduction, and sustainable development. This study examines the generation and utilization ofgases across various steel production processes in the context of China′s energy structure and thedevelopment status of its steel and chemical industries. It also reviews domestic and international casesof integrated steel-chemical production and gas resource utilization, analyzes the current state andpotential for synthesizing chemical products from steel mill gases, and proposes strategies to acceleratethe adoption of new steel-chemical integration technologies. The ultimate goal is to establish a novel,sustainable industrial ecosystem, with the steel industry as the foundation, in synergy with the chemicalindustry. Achieving the long-term goal of "Carbon Peak and Carbon Neutrality" in China′s steelindustry will depend on advancing hydrogen metallurgy, carbon capture, utilization, and storage(CCUS) technologies, along with institutional reforms and policy support. In addition, the applicationand development of life cycle assessment (LCA) research can track the carbon footprint of the steelindustry in more detail and systematically analyze its energy consumption and environmental impact.However, systematic LCA analyses of China′s steel industry are still limited. Overall, realizing China′scarbon neutrality objectives will require broader cross-disciplinary approaches and innovativestrategies. Close-
