摘要

本文综述了炼钢废气，特别是焦炉废气和高炉废气在固体氧化物电池（SOC）技术中的利用潜力。研究表明，在燃料电池或电解模式下运行的soc，为这些未充分利用的副产品的能量回收和化学生产提供了有希望的途径。甲烷和氢含量高的COG为发电和制氢提供了重要的机会，而BFG的高CO2和CO浓度使其更适合电解应用。主要挑战，如碳沉积、硫中毒和焦油污染，与缓解战略一起讨论。这篇综述强调了将SOC技术与炼钢工艺相结合的机遇和挑战，为未来的研究方向提供了见解，以优化COG和BFG的再利用，实现可持续的钢铁生产。

Utilisation of steelmaking waste gases in solid oxide cell technology: Opportunities, challenges and future directions

This review investigates the potential of utilising steelmaking waste gases, specifically coke oven gas (COG) and blast furnace gas (BFG), in solid oxide cell (SOC) technology. It is shown that SOCs, which operate in fuel cell or electrolysis modes, offer promising pathways for energy recovery and chemical production from these underutilised byproducts. COG, with its high methane and hydrogen content, presents significant opportunities for power generation and hydrogen production, while the high CO₂ and CO concentrations of BFG make it more suitable for electrolysis applications. Key challenges, such as carbon deposition, sulfur poisoning and tar contamination, are discussed alongside strategies for mitigation. This review highlights the opportunities and challenges of integrating SOC technology with steelmaking processes, offering insights into future research directions to optimise the reuse of COG and BFG for sustainable steel production.
