Technology Introduction:
This technology integrates two major strategies: hydrogen-rich blast furnace ironmaking and top gas recycling and reuse, effectively reducing blast furnace carbon emissions through both direct and indirect hydrogen-based carbon replacement reactions. By injecting hydrogen to reduce coke consumption and improve reduction efficiency, combined with top gas recovery and reutilization technologies, the overall CO₂ reduction performance is significantly enhanced.
Industry Applicability:
This integrated solution has been successfully implemented in collaboration with China Steel Corporation (CSC) for on-site production of low-carbon hot metal. By supplying low-carbon upstream materials, this technology is supporting the domestic metal products industry—including sectors such as machine tools, automotive components, and hand tools—and driving the overall industrial transition toward a net-zero carbon future.
