SUMMARY:Tecnored briquetting technologies for low carbon BF-BOF: Bio-briquette for cokemaking and catalyzed briquette for blast furnace
DESCRIPTION:The iron and steel production sector accounts for 7-9% of the total CO2 emitted worldwide, being one of the most energy-intensive and large-volume production industries. As a result, governments and companies are committed to mitigating its CO2 emissions, an important requisite for the future development of the steel industry. Most of the world's steel is obtained through the blast furnace-basic oxygen furnace (BF-BOF) route, with the blast furnace being responsible for roughly 90% of the total carbon emissions of the entire steelmaking route. However, reducing BF CO2 emissions is challenging due to the technology's high maturity and raw materials. Tecnored company has extensive experience developing cold agglomerated briquettes for its smelting reduction technology, which is 100% fed with self-reducing briquettes and fuel briquettes. With the increasing demands for CO2 reduction in the iron and steel sector and Tecnored background, two low-carbon briquetting solutions were developed for hot metal production (BF). The first one is a bio-briquette for cokemaking (BBC). The replacement of coking coals by biomass-based materials for coke production is challenging, usually limited to no more than 1-2% only. BBC has promising results indicating up to 10% replacement ratio while keeping high coke quality. The second low-carbon solution developed by Tecnored is the catalyzed briquette for blast furnace (CBB). CBB is a combination of carbonaceous sources (coking/non-coking coals, biocarbon, etc.), a catalyst (iron and calcium bearing materials) and binders, which is carbonized in mild conditions to produce a material with the ideal composition and strength for blast furnace application. The utilization of CBB associated with the sinter layers in BF has the potential to decrease reserve zone temperature hence coke consumption. In this study, the main characteristics and features of the briquetting solutions (BBC and CBB) were discussed regarding their potential for use, process impact and potential for CO2 mitigation.
