Research Area 2 focuses on the thermochemical oxidation in order to release renewable energy. This covers a wide range of scales, including the single particle, particle groups and complex flows.
In order to enable effective separation of the solid metal oxides, e.g. with conventional cyclones, the particle size must not change much during oxidation. In addition, metal leakage because of metal oxide nanoparticles must be avoided. Iron is the element of choice here.
