Title: The application of hydrogen as a reducing agent for electric arc furnace dust

The social commitment to sustainability requires the industry to improve and adapt production and recycling processes continuously. An approach to reduce greenhouse gas emissions in carbon-based reduction technology is the substitution of carbon by hydrogen. In the field of electric arc furnace dust (EAFD) recycling, the application of hydrogen is only tenuously evaluated. The thesis explores hydrogen as an alternative reducing agent for electric arc furnace dust. Thermogravimetric analyses are applied to investigate thermodynamic and kinetic fundamentals. Thus, fundamental data for subsequent technical and economic feasibility studies of hydrogen usage in EAFD recycling is provided.
