The chemical industry remains one of the world’s largest industrial energy consumers and a major source of direct industrial CO₂ emissions due to its energy-intensive processes and heavy reliance on fossil-based hydrocarbons. A more sustainable approach is to replace fossil feedstocks with bio-derived molecules and to develop more energy-efficient reactions, which often rely on heterogeneous catalysis. To analyse sustainable, heterogeneously catalysed processes, a catalytic flow channel has been designed at the laboratory for Optical Diagnostics and Renewable Energy (ODEE) that enables the investigation of near surface transport phenomena during the reaction using gas-phase Raman spectroscopy.

Within the scope of this Master thesis, a new reactor that allows the investigation of more complex flow scenarios at higher temperatures will be integrated into the existing setup and put into operation. The gas-phase temperature and composition under selected experimental conditions will be determined and compared with previously obtained results.
