Biocarbon Suitability Evaluation for Direct Injection in Blast Furnace Ironmaking

steel research international, Volume 97, Issue 4, Page 2278-2287, April 2026.
This study examines densified biocarbon for direct injection in blast furnace ironmaking to reduce greenhouse gas (GHG). Enhanced burnout performance, along with favorable reactivity and carbon structure of the combustion residue, supports its suitability for blast furnace injection. Modeling results indicate that up to a 27% reduction in GHG emissions
