Prodinger, Sebastian; Capel Berdiell, Izar; Cordero-Lanzac, Tomas; Bygdnes, Odd Reidar; Solemsli, Bjørn Gading; Kvande, Karoline; Arstad, Bjørnar; Beato, Pablo; Olsbye, Unni; Svelle, Stian (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Mordenite (MOR) zeolite, an important industrial catalyst exists in two, isostructural variants defined by their port-size, small and large-port. Here we show for the first time how a systematic, single-parameter variation ...

Kvande, Karoline; Pappas, Dimitrios; Dyballa, Michael Martin; Buono, Carlo; Signorile, Matteo; Borfecchia, Elisa; Lomachenko, Kirill A.; Arstad, Bjørnar; Bordiga, Silvia; Berlier, Gloria; Olsbye, Unni; Beato, Pablo; Svelle, Stian (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)On our route towards a more sustainable future, the use of stranded and underutilized natural gas to produce chemicals would be a great aid in mitigating climate change, due to the reduced CO2 emissions in comparison to ...

Kvande, Karoline (Doctoral thesis / Doktoravhandling, 2023)Due to poor access and energy-intensive conversion reactions, large reservoirs of natural gas are underutilized. Natural gas and biogas mainly contain small and stable hydrocarbons (light alkanes) and could be a more ...

Kvande, Karoline; Prodinger, Sebastian; Schlimpen, Fabian; Beato, Pablo; Pale, Patrick; Chassaing, Stefan; Svelle, Stian (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Abstract Direct conversion of methane to methanol (MTM) over Cu-zeolites is a so-called “dream reaction” for the chemical industry. There is still a lot that can be done in order to optimize the reaction by e.g. achieving ...

Kvande, Karoline; Prodinger, Sebastian; Solemsli, Bjørn Gading; Bordiga, Silvia; Borfecchia, Elisa; Olsbye, Unni; Beato, Pablo; Svelle, Stian (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Sending ethane over Cu-oxo sites in zeolites allows for the selective formation of ethylene in a stepwise reaction at mild conditions. Experimental results indicate that the reaction proceeds via the formation of ethanol ...

Pappas, Dimitrios; Kvande, Karoline; Kalyva, Maria Evangelou; Dyballa, Michael Martin; Lomachenko, Kirill A.; Arstad, Bjørnar; Borfecchia, Elisa; Bordiga, Silvia; Olsbye, Unni; Beato, Pablo; Svelle, Stian (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)The direct conversion of methane to methanol has the potential of substantially reducing methane emissions and flaring, as such a process might provide an alternative for remote natural gas locations. In this report, we ...

Kvande, Karoline; Garetto, Beatrice; Deplano, Gabriele; Signorile, Matteo; Solemsli, Bjørn Gading; Prodinger, Sebastian; Olsbye, Unni; Beato, Pablo; Bordiga, Silvia; Svelle, Stian; Borfecchia, Elisa (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)The direct activation of methane to methanol (MTM) proceeds through a chemical-looping process over Cu-oxo sites in zeolites. Herein, we extend the overall understanding of oxidation reactions over metal-oxo sites and C–H ...

Dyballa, Michael Martin; Thorshaug, Knut; Pappas, Dimitrios; Borfecchia, Elisa; Kvande, Karoline; Bordiga, Silvia; Berlier, Gloria; Lazzarini, Andrea; Olsbye, Unni; Beato, Pablo; Svelle, Stian; Arstad, Bjørnar (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)This contribution clarifies the overoxidation-preventing key step in the methane-to-methanol (MTM) conversion over copper mordenite zeolites. We followed the methane-to-methanol conversion over copper mordenite zeolites ...
