Correlation of Catalyst Morphology with Attrition Resistance and Catalytic Activity of Fischer-Tropsch Catalysts
(Master thesis, 2013)Three alumina based support materials for the Fischer-Tropsch synthesis (FTS) catalyst has been prepared and investigated. The three support materials were prepared in order to obtain different mechanical strengths, ... -
Corrosion and degradation in amine based post-combustion CO2 capture
(Doctoral thesis at NTNU;2016:98, Doctoral thesis, 2016)Consumption of coal is expanding, and without CO2 capture and storage (CCS) or some other advanced coal combustion system, the most emission intensive gas, CO2, will continue to worsen climate change. Among the various ... -
Corrosion and degradation in MEA based post-combustion CO2 capture
(Journal article; Peer reviewed, 2016)Two of the main challenges in post-combustion CO2 capture with ethanolamine are solvent degradation and material corrosion. It has been shown that there is a correlation between degradation and corrosion. The present paper ... -
Corrosion Evaluation of MEA Solutions by SEM-EDS, ICP-MS and XRD
(Journal article; Peer reviewed, 2016)The target of this work is to evaluate three analytical techniques, ICP-MS, SEM-EDS and XRD, which can be applied in corrosion monitoring of ethanolamine based post-combustion CO2 capture plants. The work is based on ... -
Corrosion of Copper and Oxidation of Dielectric Liquids in High Voltage Transformers
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:196, Doctoral thesis, 2013)Breakdowns in high voltage transformers are of major concern. It is therefore a goal to prevent this from happening. Chemical degradation (e.g. oxidation, hydrolysis and corrosion) of the insulation systems and windings ... -
