Recently a special attention is being paid on the Hydrogen Direct Reduction (H-DR) process to minimize the CO2 emissions in ironmaking processes. Despite the fact that many components of the H-DR/EAF setup have been tested in industrial settings, key challenges, such as the high cost of renewable electricity still remain for the process. Biomass, as a renewable source of heating and reducing, is also considered to reduce CO2 emissions and promote reductions. Thus, in this study, one type of torrefied biomass was used as an embedded reducing agent to prepare pellets. The produced self-reducing pellets were further isothermally reduced under H2 involved atmospheres at 750-950⁰C. Mass loss, reduction degree, metallization degree and volume change were examined in a first approach to estimate the reduction process and mechanism.
