The main intention of the work was to do investigations of mechanical ... -
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 ... -
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 ... -
Iron supported on beaded carbon black as active, selective and stable catalyst for direct CO<inf>2</inf> to olefin conversion

Isolation and Characterization of Oil-Soluble Calcium Naphthenates in North Sea Heavy Crude Oil
(Master thesis, 2014)Naphthenic acids are a diverse group of saturated mono- and polycyclic carboxylic acids that may account for as much as 10-12 weight % of crude oil. During production at several newer oil fields, there have been discoveries ... -
Isolation of thermophilic enzyme-producing Parageobacillus bacteria from chipped woody waste
(Journal article; Peer reviewed, 2019)The morphological and biochemical properties were investigated for 18 types of thermophilic bacteria isolated from a woody-chip pile at a wood processing plant in Northern Russia. Genetic fingerprinting and 16S rRNA ... -
Isolation, Characterization and Prediction of Calcium Naphthenates in High Acid Crude Oils
(Master thesis, 2015)Calcium naphthenates in crude oil causes operational problems in refineries and lowers the market price for oil production companies. This Master s thesis aims to study the naphthenic acids who form calcium naphthenates ... -
Iterative sub-network component analysis enables reconstruction of large scale genetic networks
(Journal article; Peer reviewed, 2015)Background: Network component analysis (NCA) became a popular tool to understand complex regulatory networks. The method uses high-throughput gene expression data and a priori topology to reconstruct transcription factor ... -

Jet fuel range hydrocarbon production from propanal: Mechanistic insights into active site requirement of a dual-bed catalyst
(Peer reviewed; Journal article, 2020)Utilization of sustainable biomass to produce jet fuel range hydrocarbons is imperatively needed to mitigate CO2 emissions and to liberate the over-reliance on fossil resources. Using propanal as the feedstock, an excellent ... -
Jet Pump Technology for Enhanced Oil Production
(Master thesis, 2019)Aldrende oljefelt opplever ofte fallende produksjon i enkelte brønner som følge av lavere trykk, økende vannmengder og endrede reservoaregenskaper. Ula-platformen har vært i drift siden 1986 og har flere slike brønner. ... -
Kinetic and Deactivation Studies of Hydrodesulfurization Catalysts
(Dr. ingeniøravhandling, 0809-103X; 2002:148, Doctoral thesis, 2002)Hydrodesulfurization is an important part of the hydrotreating process. More stringent regulations on the quality of fuels bring new requirements to the catalytic processes. The removal of sulfur has become a key issue in ... -
Kinetic modeling of dynamic changing active sites in a Mars-van Krevelen type reaction: Ethylene oxychlorination on K-doped CuCl2/Al2O3
(Peer reviewed; Journal article, 2020)A kinetic model was developed by taking into account the dynamic nature of the active sites in Mars–van Krevelen type catalytic reactions to predict the evolution of the reactant and product composition in the gas phase ... -
Kinetic Modeling of Oxychlorination Reaction
(Master thesis, 2016)Polyvinyl chloride is a widely produced plastic polymer due to its various applications and relatively low cost. Oxychlorination of ethylene to 1,2-dichloroethane is an important step in the production of vinyl chloride ... -
