1 1 K J E M I 1 2 0 2 3 model for the formation of dimethyl ether from methanol over a zeolite catalysts. By bridging reaction mechanisms from theory with macroscale transport models, he is building a model to simulate both reaction and deactivation for the conversion of methanol to hydrocarbons. Karoline Kvande ((UiO, in collaboration with Haldor Topøe A/S within the iCSI center) presented new results on the stepwise conversion of ethane to ethylene over copper loaded zeolites. This represents an extension on previous studies of the oxidation of methane to methanol using the same catalyst system. Finally, Song Lu (UiS) closed the first day of the symposium by presenting recent progress on the development of carbon supported nickel single atom catalysts for the electrocatalytic reduction of carbon dioxide. The oral session was followed by 9 poster presentations before the symposium dinner. MOF synthesis and characterization The second day started with plenary speaker Petra Ágota Szilágyi (UiO). She discussed strategies for MOF synthesis and characterization using a number of MOF-metal host-guest composites. She summarized the effect of pore size and functionalities on the ability of the frameworks to incorporate, control the geometry of, and interact with the guest particles. She used some examples to demonstrate how the above effects contribute to the catalytic performance of the host-guest composite materials in selected reactions. Tomás Cordero Lanzac (UiO, within the context of EU Horizon 2020 COZMOS project) made a very comprehensive presentation on CO2 conversion to hydrocarbons. The work spans from laboratory catalyst fundamental study, catalyst scale-up, kinetic modeling, reactor design, plant simulation, and LCA analysis of the process. Björn Frederik Baumgarten (NTNU) presented their recent work on CO2 hydrogenation to methanol on indium-based catalysts, using alginate as precursor and benchmarked with the impregnated catalysts. He proposed to use in-situ mass analyzer for future coking study during further MTO process. Bjørn Gading Solemsli (UiO, within the iCSI center) presented the use of Cu-exchanged mordenite (MOR) and ZSM-5 (MFI) microporous zeolites for the stepwise methylation of propylene, ethylene and benzene, building on previous studies of the direct, stepwise methane-to-methanol reaction. Vladyslav Shostak (UiO) made a presentation on the transient adsorption-diffusion models for hydrocarbon transport in microporous materials, using C2-C4 hydrocarbons in ZSM-5 as case study. He concluded that accounting for microporous diffusivity in models significantly improved the description of gas transport. Ljubiša Gavrilović (IFE, in collaboration with NTNU, funded by NFR) presented the application of a dynamically operated Fischer-Tropsch reactor where the produced water is removed by zeolite adsorbents to increase CO conversion and higher hydrocarbon (wax) selectivity while protecting the Co-based FT catalysts from oxidation. Finally, Hilde Johansen Venvik (NTNU) introduced the Nordic Catalysis Symposium in 2024, which will be organized in Stavanger, and the European Congress om Catalysis in 2025, which will be organized in Trondheim. ● Professor Petra Ágota Szilágyi, UiO Professor Hilde J.
