Novel approach of advanced characterization, dedicated synthesis and theoretical modelling on commercially relevant Fischer-Tropsch catalysts for production of sustainable fuels & chemicals: Bridging industry and academia — •Anna Zimina1, 4, Rabia Elbuga-Ilica1, Dan Zhao1, Cherie Hsu1, Erisa Saraci1, Moritz Wolf1, Felix Studt1, Michael Cleays2, Denzil Moodley3, and Jan-Dierk Grunwaldt1, 4 — 1IKFT-KIT / Eggenstein-Leopoldshafen / Germany — 2University of Cape Town / South Africa — 3Sasol South Africa / South Africa — 4ITCP-KIT / Karlsruhe / Germany
Power-to-liquid processes can be considered the key for renewable electricity-based liquid fuel generation. Various olefins can be synthesized via Fischer-Tropsch synthesis. The CARE-O-SENE consortium that connects German and South African partners is driven to accelerate the development of cobalt-based FT catalysts for green and efficient production of sustainable aviation fuel. For efficient development, systematic characterization of Co-based catalysts, especially in-situ and operando is essential to derive structure-activity relationships in reliable manner. X-ray absorption spectroscopy, X-ray diffraction, magnetometry and Raman spectroscopy are a highly promising tool as structural changes of active species, support and adsorbents can be observed in heterogeneous catalysts at work. Advanced studies of commercially relevant materials for FTS and model structures to mimic the atomic structure of active cobalt, promoter and support were performed and combined with theoretical modelling.
