Correlation of Catalyst Morphology with Attrition Resistance and Catalytic Activity of Fischer-Tropsch Catalysts
Fiske, Thomas Haukli (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 of Copper and Oxidation of Dielectric Liquids in High Voltage Transformers
Tronstad, Ingvild (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 ... -
Cross-linking oxidized cellulose nanofibrils for the formation of stable hydrogel structures
Pettersen, Sigurd Rolland (Master thesis, 2013)The main goal of this project was to investigate whether the elastic properties of microfibrillated cellulose (MFC) suspensions pre-treated by TEMPO-mediated oxidation could be controlled by inducing cross-links between ... -
