| Abstract Scope |
In the overall endeavor to become carbon neutral, the transition from fossil fuels to biocarbon materials is one of the many actions being taken by the silicon and ferroalloy industry. When substituting metallurgical coke or coal with more fragile biocarbon, the lower mechanical strength results in the production of more detrimental fines. Additionally, biocarbon has a lower density, leading to a faster throughput in furnaces. Research has primarily focused on various reactivities, such as CO₂ reactivity[1,2], SiO reactivity[3], and slag reactivity[4]. This presentation will demonstrate how CO₂ reactivity is influenced by the type of carbon used, with a particular emphasis on how alkalis increase the CO₂ reaction rate for fossil carbon more significantly compared to biocarbon. Regarding slag reactivity, it has typically been observed that charcoal reacts slower than metallurgical coke. |
