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

Study on briquetting and gasification reactivity of carbon-rich residue from coal gasification fine slag

International Journal of Coal Preparation and Utilization
Gasification has emerged as a viable strategy for large-scale disposal of coal gasification fine slag (CGFS). In this work, the carbon-rich residue (CR) of CGFS was briquetted, and the effects of binder addition, moisture content and height-to-diameter ratio (H/D) on mechanical strength of briquetted carbon-rich residue (BCR) were investigated through ...
