Abstract

Language:

The iron and steel industry is still dependent on fossil coking coal, with approximately 70% of steel production relying directly on fossil coal and coke inputs, contributing ~7% of global CO2 emissions. Reducing these emissions has become a priority for the sector, driven by governmental commitments such as the Kyoto Protocol. This review discusses the utilization of auxiliary carbonaceous materials in blast furnaces and other iron-making technologies as an efficient means to decrease coke consumption and CO2 emissions. The results indicate that the partial substitution of top-charged coke with nut coke, lump charcoal, or carbon composite agglomerates not only decreases dependency on virgin fossil carbon but also enhances blast furnace performance and productivity. Additionally, substituting pulverized coal with waste plastics or renewable materials like biomass helps mitigate CO2 emissions due to their higher hydrogen content compared to fossil carbon. This injection improves combustion efficiency, reduces coke consumption, and necessitates the recycling of integrated steel plant byproducts to improve economic and environmental outcomes. The findings highlight the potential of these technologies in achieving sustainability within the iron and steelmaking domains.
