Reducing CO2 Emissions in Metallurgy with Renewable Biocarbon
Short Introductive summary
Carbon is widely used as a reducing agent in the metallurgical industry, where it plays a critical role in the production of metals such as silicon, ferroalloys (e.g., FeSi and FeMn), and aluminum. In Mn and Fe/Si production, carbon acts as a reductant in carbothermic reactions, while in aluminum production, it serves as a crucial component in anodes, cathodes, and as packing material during anode baking. Traditionally, this carbon has been sourced from fossil-based materials, but biomass-derived carbon presents a promising, renewable alternative that could significantly reduce CO2 emissions, making metal production more sustainable. As the industry shifts towards renewable options, bio-carbon has gained attentionnot only as an energy source but also as an indispensable reactant in metal-forming processes. Each metallurgical application requires bio-carbon with specific properties, with characteristics like mechanical and thermal strength being essential across all sectors. This work provides an overview of relevant carbon properties and methods for their characterization, along with an evaluation of how these properties may impact various metallurgical processes when introducing
