Synthesis and Evaluation of K-Promoted Co3-xMgxAl-Oxides as Solid CO2 Sorbents in the Sorption-Enhanced Water−Gas Shift (SEWGS) Reaction
Arstad, Bjørnar; Blom, Richard; Håkonsen, Silje Fosse; Pierchala, Joanna; Cobden, Paul; Lundvall, Fredrik; Kalantzopoulos, Georgios N.; Wragg, David; Fjellvåg, Helmer; Sjåstad, Anja Olafsen (Peer reviewed; Journal article, 2020)Hydrogen is essential in a variety of large-scale chemical processes. As a carbon-free energy carrier, hydrogen has a potential for wide use within power production and transportation. However, most of the recent production ... -
Synthesis-Structure-Activity Relationship in Cu-MOR for Partial Methane Oxidation: Al Siting via Inorganic Structure-Directing Agents
Prodinger, Sebastian; Kvande, Karoline; Arstad, Bjørnar; Borfecchia, Elisa; Beato, Pablo; Svelle, Stian (Peer reviewed; Journal article, 2022)In the pursuit of controlling the propensity of Cu-mordenite (MOR) for the selective oxidation of CH4, we take a closer look at intrinsic zeolite parameters. Via synthesis design, we vary the relative proportion of Al ... -
The nuclearity of the active site for methane to methanol conversion in Cu-mordenite: a quantitative assessment
Pappas, Dimitrios; Martini, Andrea; Dyballa, Michael Martin; Kvande, Karoline; Teketel, Shewangizaw; Lomachenko, Kirill A.; Baran, Rafal; Glatzel, Pieter; Arstad, Bjørnar; Berlier, Gloria; Lamberti, Carlo; Bordiga, Silvia; Olsbye, Unni; Svelle, Stian; Beato, Pablo; Borfecchia, Elisa (Journal article; Peer reviewed, 2018) -
Thermogravimetric Analysis – A Viable Method for Screening Novel Materials for the Sorbent Enhanced Water-gas Shift Process
Lundvall, Fredrik; Kalantzopoulos, Georgios N.; Wragg, David; Arstad, Bjørnar; Blom, Richard; Sjåstad, Anja Olafsen; Fjellvåg, Helmer (Peer reviewed; Journal article, 2017)Pre-combustion CO2 capture technologies are becoming viable alternatives to more conventional post-combustion capture by gas emissions scrubbing. The sorbent enhanced water-gas shift (SEWGS) process is a promising future ... -
Tuning the material and catalytic properties of SUZ-4 zeolites for the conversion of methanol or methane
Dyballa, Michael Martin; Pappas, Dimitrios; Borfecchia, Elisa; Beato, Pablo; Olsbye, Unni; Lillerud, Karl Petter; Arstad, Bjørnar; Svelle, Stian (Peer reviewed; Journal article, 2018)This work describes the synthesis and investigation of improved SUZ-4 catalysts (SZR framework) and their application in methanol-to-olefins and methane-to-methanol conversion. We report boron containing, dealuminated and ... -
Understanding and Optimizing the Performance of Cu‐FER for the Direct CH4 to CH3OH Conversion
Pappas, Dimitrios; Borfecchia, Elisa; Dyballa, Michael Martin; Lomachenko, Kirill A.; Martini, Andrea; Berlier, Gloria; Arstad, Bjørnar; Lamberti, Carlo; Bordiga, Silvia; Olsbye, Unni; Svelle, Stian; Beato, Pablo (Journal article; Peer reviewed, 2018) -
Use of metal-organics based solvents for CO2 capture
Heyn, Richard H; Aronu, Ugochukwu Edwin; Vevelstad, Solrun Johanne; Hoff, Karl Anders; Didriksen, Terje; Arstad, Bjørnar; Blom, Richard (Journal article; Peer reviewed, 2014)There are a number of metal-organic compounds that can loosely be considered CA mimics and which are known to absorb CO2 directly from the atmosphere. The metal-organic complex, {Zn[N[CH2(2-py)]3](μ-OH)}2(NO3)2 (I), is one ... -
Zeolite surface methoxy groups as key intermediates in the stepwise conversion of methane to methanol
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; 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 ...
