Toward Fossil‐Free Steelmaking: Overview of Physiochemical Properties of Hydrochar and Its Application in Blast Furnace and Electric Arc Furnace Processes

cScience, Volume 1, Issue 1, December 2025.
ABSTRACT The steel industry is among one of the largest CO2 emitters in the world. To meet climate targets, replacing fossil‐based carbon with renewable biocarbon in metallurgical processes, particularly in blast furnaces (BFs) and electric arc furnaces (EAFs), has emerged as a viable short‐ to mid‐term solution.

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 ...
