Japan started the national project "COURSE 50" for CO2 reduction in the 2000s. This project aimed to establish novel technologies to reduce CO2 emissions with partially utilization of hydrogen in blast furnace-based ironmaking by 30% by around 2030 and use it for practical applications by 2050. The idea is that instead of coke, hydrogen …

Until the 1950s of the last century, the oxidized iron ores that were loaded into the blast furnace had granulometries within 10 and 120 mm. However, the depletion of high-grade iron ore sources has made necessary the utilization of concentration processes with the purpose of enriching the iron ore. Because of these processes, a fine …

The iron-ore agglomerates are normally tested in a reduction gas consisting of 35% CO, 5% CO2 and 60% N2 by volume at 1,000. Heating is done in a nitrogen atmosphere, after which the agglomerates are reduced isothermically for a certain length of time. A couple of the agglomerates are then compressed one at a time -- still at …

The main difference between iron ore agglomerates and CCAs is the rate-controlling step of the reduction of iron oxides. In case of iron ore agglomerates, the reduction takes place at gas-solid interfaces. Reducing gases move from the gas stream to the agglomerate surface then to the interior surface of the pores. In CCAs, carbon is …
