DC2: Carburization and melting behaviour of hydrogen-based direct reduced iron
Project title: Carburization and melting behaviour of hydrogen-based direct reduced iron (WP1)
Host Institution: TU Delft
Supervisors: Yongxiang Yang (TUD) – Co-supervisors: Neslihan Dogan (TUD), Jan van der Stel (TATA), Muxing Guo (KUL)
- Design, study and optimize various potential carburization methods for both iron-ore pellets and H-DRI;
- Determine the carburization mechanisms and kinetics of the pellets and the H-DRI for the most promising carburization methods;
- Evaluate the melting behaviour of the carburized pellets;
- Novel carburization methods, aiming for both high process efficiency (time, temperature, complexity) and optimal resulting H-DRI characteristics (C content, melting temperature);
- Identification of the maximum carburization level and the process parameters controlling the carbon content in the H-DRI pellets for the developed carburization methods;
- Established reaction kinetics and mechanisms of the most promising carburisation processes;
- Melting temperature of the various carburized pellets;
