Ethylene Oxychlorination on CuCl2 based Catalysts: Mechanism and Kinetics
(Doctoral theses at NTNU;2021:114, Doctoral thesis, 2021)Ethylene oxychlorination is one of the major industrial sources of vinyl chloride, the monomer of poly-vinyl chloride (PVC). The oxychlorination reaction is catalysed by alumina supported, CuCl2 based catalysts which ... -
European standardization efforts from FAIR toward explainable-AI-ready data documentation in materials modelling
(Chapter, 2023)Security critical AI applications require a standardized and interoperable data and metadata documentation that makes the source data explainable-AI ready (XAIR). Within the domain of materials modelling and characterization, ... -
Evaluating the possibility of high-pressure desorption of CO2 via volatile co-solvent injection
(Peer reviewed; Journal article, 2021)This work evaluates the possibility of employing a volatile co-solvent injection for recovering CO2 from loaded monoethanolamine at 120 °C under pressures above those achievable through regular desorption processes. This ... -
Evaluation of a phase change solvent for CO2 capture: Absorption and desorption tests
(Journal article; Peer reviewed, 2014)A blend of a tertiary amine (DEEA) and a diamine (MAPA) was studied in a screening apparatus for preliminary absorption tests. Two immiscible liquid phases were formed upon CO2 loading and the system was shown to have large ... -

Evaluation of anti-agglomerate hydrate inhibitor in water-in-crude oil emulsions of different water cut
(Peer reviewed; Journal article, 2020)A commercially available anti-agglomerant (AA) was evaluated in water-in crude oil (W/CO) emulsions at different water cut. The injection of an AA to an emulsion affects the induction time and rate of hydrate formation. ... -
Evaluation of different block-copolymers coatings of iron oxide nanoparticles by flash nanoprecipitation
(Master thesis, 2023)Nanoparticles (NPs) offer unique possibilities for medical applications, including the controlled release of cancer drugs, the use as imaging contrast during imaging procedures or the hyperthermic treatment of cancer cells. ... -
Evaluation of ORR active sites in nitrogen-doped carbon nanofibers by KOH post treatment
(Journal article; Peer reviewed, 2018)Oxygen reduction on N-doped carbon nanomaterials is believed to take place at either N-centered active sites (C-Nx) or Fe-centered active sites (Fe-Nx). In this work the origin of the oxygen reduction on nitrogen-doped ... -
Evaluation of Reoxidation Thresholds for γ-Al2O3-Supported Cobalt Catalysts under Fischer - Tropsch Synthesis Conditions
(Journal article; Peer reviewed, 2017)Size-dependent phenomena at the nanoscale influence many applications, notably in the science of heterogeneous catalysis. In cobalt-based Fischer–Tropsch synthesis (FTS), the size of Co nanoparticles (NPs) dictates to a ... -
Evaluation of Solvent Degradation in Amine-Based Post-Combustion Capture Process Simulations.
(Journal article, 2022)It is important to limit solvent degradation in amine-based post combustion capture systems, as it can lead to challenges, such as solvent losses, reductions in process performance, increased emissions, and corrosion of ... -
Evaluation of solvents for upgrading and conditioning of high hydrogen sulphide content biogas to biomethane standards
(Master thesis, 2023)Det er en økende interesse for produksjon av biogass fra biomasse med høyt svovelinnhold. Det er avgjørende å separere ut CO2 og H2S før biogassen kan brukes. I denne masteroppgaven ble oppgradering og kondisjonering av ... -
