The iron and steel industry are confronted with pressing challenges. Historically, the industry has heavily relied on carbon-intensive blast furnaces for iron-ore reduction, contributing significantly to greenhouse gas emissions. However, with global sustainability goals and stricter environmental regulations, there's a growing urgency for innovation. Tata Steel in the Netherlands is dedicated to revolutionizing iron manufacturing by transitioning from coal to gas-based direct reduction processes (DRI), utilizing hydrogen. This approach promises a substantial reduction in carbon emissions compared to traditional blast furnace methods, aligning with the industry's commitment to environmental responsibility.
To achieve these goals, it is imperative to understand the intricate chemical reactions occurring on the iron surfaces during the direct reduction process. This understanding is crucial for ensuring controlled product quality and throughput. Inconsistencies can lead to inefficiencies, increased energy consumption, and lower product quality, which the steel industry can ill afford.
Our project focuses on developing accurate particle models, validated through experiments, and scaling it up to a comprehensive process model. This model will simulate industrial direct reduction shaft furnace processes under various operating conditions, including temperature, pressure, pellet chemistry, and gas composition when transitioning from natural gas to hydrogen based DRI production.

About the departmentThe Sustainable Process Technology (SPT) group is part of the Faculty of Science and Technology at the University of Twente. We conduct experimental and theoretical research in the areas of biomass conversion, affinity separations, plastic recycling, water, and CO2 capture and conversion. We combine our expertise in different disciplines (process design, chemistry, catalysis, modelling, engineering) to contribute to the development of sustainable chemical processes.
About the organisationThe Faculty of Science & Technology (Technische Natuurwetenschappen, TNW) engages some 700 staff members and 2000 students in education and research on the cutting edge of chemical technology, applied physics and biomedical technology. Our fields of application include sustainable energy, process technology and materials science, nanotechnology and technical medicine. As part of a people-first tech university that aims to shape society, individuals and connections, our faculty works together intensively with industrial partners and researchers in the Netherlands and abroad, and conducts extensive research for external commissioning parties and funders. Our research has a high profile both in the Netherlands and internationally and is strengthened by the many young researchers working on innovative projects with as doctoral candidates and post-docs. It has been accommodated in three multidisciplinary UT research institutes: Mesa+ Institute, TechMed Centre and Digital Society Institute.
