Investigations of molybdenum-promoted manganese-based solid sorbents for H2S capture
(Peer reviewed; Journal article, 2020)The promotion effect of Mo-addition to alumina-supported Mn-based sorbents for high-temperature desulphurization was explored. A series of Mn-based sorbents with fixed Mn-loading and different Mo-loadings were prepared by ... -
Investigations of Pd3Au(100) as a catalytic model system
(Master thesis, 2018)Catalysts are defined as materials that lowers the activation energy of a reaction, without being consumed. In heterogeneous catalysis they are commonly transitions metals which have been refined to small particles using ... -
Investigations of PdAu membranes and model systems for production of pure hydrogen
(Master thesis, 2015)Hydrogen production from carbon-containing energy sources can capture the CO2 on site, and therefore reduce the contribution to global warming. The only emission when energy is produced through a fuel cell is H2O. Another ... -
Investigations of the methanol to formaldehyde (MTF) reaction over silver
(Doctoral theses at NTNU;2021:206, Doctoral thesis, 2021)Formaldehyd har lettgjenkjennelig lukt, er det enkleste av aldehydene og ble først oppdaget av Butlerov i 1859. Industriell framstilling av formaldehyd ble utviklet i løpet av 1900-tallet og molekylet har med sin høye ... -
Investigations on the Applicability of Membrane Introduction as a Sampling Technique for Oil in Air and Water with Flame Ionization Detector (FID) and Mass Spectrometry (MS) Detection
(Master thesis, 2012)During a membrane introduction (MI) analysis the analytes are separated from the bulk matrix (e.g. air or water) by a semi-permeable membrane and transported to the detector by a carrier gas (usually helium). The most ... -
An Invitation on Characterization of H<inf>2</inf>-Reduced Bauxite Residue and Recovering Iron through Wet Magnetic Separation Processes
(Peer reviewed; Journal article, 2023)Recovering iron from the bauxite residue (BR) is one of the long-standing challenges in the mining industry. However, there is a substantial lack of information in the literature regarding sample properties and iron ... -
Influence of H2 on the Oxygen-Assisted Dehydrogenation of Ethane over Al2O3-supported Pt–Sn Catalysts
(Journal article; Peer reviewed, 2018)The oxygen-assisted dehydrogenation of ethane at 650 °C shows that adding Sn to the Pt catalyst results in increased conversion and selectivity to ethylene. Even the smallest amount of tin (0.16 wt%) has a significant ... -
