Utilization of Renewable Carbon in Electric Arc Furnace-Based Steel Production: Comparative Evaluation of Properties of Conventional and Non-Conventional Carbon-Bearing Sources

Conventional (anthracite, calcined petroleum coke, and coke) non-conventional (biochar, biocokes (3 wt.% torrefied wood, 3 coke + charcoal)) carbon-bearing sources have been studied for their use in electric arc furnace (EAF)-based steel production. Commonly, the of carbon EAFs, one important properties is content fixed carbon, release volatiles as well elemental composition inorganics. The six were analyzed by determining proximate analysis, X-ray fluorescence analysis (XRF), reactivity index (CRI), strength after reaction with CO2 (CSR), Brunauer–Emmett–Teller (BET) specific surface area Barrett–Joyner–Halenda (BJH) pore size volume ash chemical optical scanning microscopy, Raman spectroscopy diffraction (XRD) analysis. results indicate biocoke a promising option to replace conventional sources. In sample set, volatiles, similar despite total difference additives. Additionally, additives did not significantly affect indices, but slightly decreased CO2. Carbon-bearing characterized terms structural properties.
