Enhancing poisoning resistance and catalyst stability in dehydrogenation reactions through SCALMS (A06)

• Subject Area: Technical Chemistry ; Physical Chemistry of Solids and Surfaces, Material Characterisation
• Term: since 2021
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 431791331

A06 focuses on the technical dimension of SCALMS by exploring quantitatively the expected enhanced poisoning resistance and stability in dehydrogenation catalysis. For the specific case of isobutane dehydrogenation, we will perform systematic poisoning experiments under surface science and technical conditions. The data will be com-pared to traditional catalysts. Spectroscopic and reaction engineering studies will be applied to determine the concentration, reactivity, and regenerability of active sites of the SCALMS systems after contact with defined amounts of traditional poisons or after exposure to conditions favouring coke formation. We will also investigate ternary SCALMS to elucidate the effect of further alloying and dissolution on the adsorption strengths, reactivity, and stability.
