Research Topics Reaction Engineering
The energy production by renewables is fluctuating which gives rise to concepts, such as Power-To-Gas (PTG) or Power-To-Liquid (PTL), which could be used to save excess energy in form of chemicals. The electrical energy is converted to hydrogen via electrolysis. Subsequently, the hydrogen, together with a carbon source, can, for instance, be converted to methane via methanation or to artificial fuels via Fischer-Tropsch synthesis (FTS).
We use imaging techniques, such as NMR or micro-tomography, as well as computational fluid dynamics (CFD), to investigate the influence of support materials on the reaction and to intensify the process. These results could be equally transferred towards other reaction systems.
Open cell foams, often called sponges, are an ideal choice as monolithic support materials for catalysts. Their high porosity, continuous solid phase, high specific surface area, as well as the possibility for radial dispersion, make them highly suited as support for highly exothermic reactions.
We use computational fluid dynamics (CFD) as well as nuclear magnetic resonance (NMR) to predict and visualize heat and mass transfer as well as velocity, temperature and concentration profiles. The morphology of sponges is usually obtained with micro computer tomography. Our overall aim is to investigate the influence of structural parameters of the sponges on the the transport processes within them and on the efficiency of highly exothermic gas and multiphase reactions.
