IKFT 01-2023 Master Thesis: Deactivation of Methanol Synthesis Catalysts – Introducing impurities from different H2/CO2 sources

By using H2 or mixtures of synthesis gas CO/CO2/H2), which have been produced by solar‑powered methods, it is possible to synthesize methanol in a renewable manner. Methanol itself is an important key component for the renewable transformation of the chemical industry, but can also yield synthetical fuels. For this, efficient and long‑term stable catalysts, based on Cu/ZnO are necessary. The deactivation of these systems is influenced by several factors. The most important effect is thermal or water‑induced sintering of the active metal. Impurities, such as sulfur and chlorine compounds are also known for their detrimental effects. As part of the InnoPool project “Solar Hydrogen – pure & compressed”, we use hydrogen from different solar‑based sources for methanol synthesis and compare their effects on catalysis and material stability. For this objective, a setup has been constructed and tested succesfully. It is to be expanded to introduce impurities in an exact manner. Afterwards, first test should be conducted and used catalyst material has to be analysed under strict inert conditions.
