Potential for Reducing Emissions by Regulating O2, CO, and H2O in the Recirculation Gas in Iron Ore Sintering

steel research international, EarlyView.
This study investigates the potential for reducing emissions during the sintering process by selectively adjusting the O2, CO, and H2O content in the recirculation gas. Adjusting these components positively affects the sintering process, enabling the coke breeze content in the sinter mixture to be reduced.

Sequential Reduction of Chromite Pellets Using Hydrogen and Silicon Carbide for Carbon Emission Abatement During Ferrochrome Production

steel research international, EarlyView.
H2 prereduction selectively metallizes Fe in UG2 chromite pellets at 1100°C, while silicon carbide becomes active at 1300°C to convert remaining Cr2O3 to carbides and promote Cr metallization. By separating the roles of H2 and SiC, the sequential route reaches up to 65.7% Cr metallization and suppresses in‐furnace CO generation by ≈75% versus ...

Barriers to Steel Decarbonization

steel research international, EarlyView.
Main identified barriers to steel decarbonization Carbon dioxide (CO2) emissions are a leading contributor to global climate change, necessitating urgent mitigation strategies. While various metrics—such as total national emissions, per‐capita output, and historical contributions—define responsibility, determining accountability remains complex ...
