Background
The application of hydrogen gas (H2) for reduction has been a very promising method to process metal oxides. Based on preliminary results, the enviromental friendly reduction of TeO2 should be investigated in this master thesis, focusing on kinetic modeling and experiment validation
Job Definition
– Conducting reduction experiments with parameter variations
– Characterising products using SEM imaging, XRD phase analysis
– Kinetics analysis based on several solid-gas reaction model
– Provide an indepth understanding of the process, enabling optimisation for pilot scale tests
Topic
A green process for up-cycling secondary Aluminium casting alloys

M.Sc. Bo Yang

Background
The recycling of Al alloys has important economic and environmental incentives. To meet future demands for high-grade Al, a new up-cycling method is needed to upgrade the casting Al alloy to a level similar to that of wrought Al alloy. This promotes a balanced aluminium alloy cycle in the automotive industry.
Job Definition
The work will start with an elaborate literature review. Based on thermo-dynamic calculations (FactSage), additives are selected and fractional crystallization processes are used to remove the high levels of alloying elements (Fe, Cu, etc.). The additives will promote the formation of iron-rich intermetallic compounds and facilitates their precipitative separation. Fractional crystallization processes (e.g. Cooled finger process) will further separate other alloying elements.work

M.Sc. Joscha Kortmann
Background
In this thesis, the possibility of thermochemical treatment of various mineral fine fractions is investigated. Due to their heterogeneity, potential contamination and non-economic use, they are not often integrated into circular economy systems. With thermal conditioning, there are promising approaches for the utilization of these materials in building material applications. The aim is to identify suitable mixing ratios for different mineral fine fractions and to determine the required process parameters. For achieving this, thermochemical data sets are created using FactSage and then analyzed using machine learning methods. This approach enables a much more efficient search for possible process windows and opens up the opportunity to identify previously undiscovered options.
Job Definition
Data set generation: Creation of thermochemical data sets using FactSage software in previously defined process windows.
Modeling: Application of machine learning methods to analyze the generated data sets and identification of optimal process parameters and mixing ratios through modeling results.ork
