The DLR Institute for Future Fuels is developing processes for an energy system of the future that does not require fossil fuels. Because of their high energy density, liquid fuels can continue to play a particularly important role in this. Solar-powered redox cycles can be used to produce synthesis gas (a mixture of hydrogen and carbon monoxide), which is further processed into a CO2-neutral fuel in a subsequent process step.

The effectiveness of such a process in discontinuous operation has already been demonstrated on a larger scale. Heat recovery at high temperatures plays an important role in increasing efficiency. Theoretical studies have shown that an undesirable side reaction and associated undesirable oxygen transport can occur during this heat recovery step. In order to be able to better quantify the effects of this reaction, it is to be investigated experimentally within the framework of the advertised master's thesis. A test rig developed for this purpose will be used to investigate the extent and speed of the reaction under realistic operating conditions. In addition to planning and conducting the experiments, your tasks will also include their evaluation.
