Abstract

Language:

In the pursuit of carbon-neutral steelmaking, the need for alternative reducing agents such as hydrogen and bio-based fuels has gained prominence as substitutes for metallurgical coke in blast furnace operations. This study proposes a detailed six-phase multicomponent mathematical model to evaluate the impacts of combined hydrogen-rich gas and pulverized charcoal injection on the efficiency of blast furnace practices. The methodology involves analyzing operational parameters and their influence on the equivalent fossil CO2 emissions during the steelmaking process. Results indicate significant reductions in CO2 emissions, demonstrating the potential of hydrogen-based technologies, with emission reductions reaching up to 45.9% under optimized conditions. The findings highlight the feasibility of integrating cleaner production methods within traditional steelmaking frameworks, paving the way for more sustainable industrial practices. This research contributes to the ongoing discourse on carbon neutrality in heavy industries and offers insights for future implementations of innovative carbon utilization technologies.
