Biodiesel Production by the Esterfip-H Process: Modelling, Optimization and Control Structure
Øien, Marianne (Master thesis, 2013)For this master's thesis the Esterfip-H process for biodiesel production from rapeseed oil have been modelled in Chemcad. Esterfip-H is a two fixed-bed reactor system using a heterogeneous catalyst of zinc aluminate oxide ... -
Calcium Based CO2 Acceptors for Sorption Enhanced Steam Methane Reforming
Sultana, Kazi Saima (Doktoravhandlinger ved NTNU, 1503-8181; 2011:317, Doctoral thesis, 2011)Conversion of natural gas and light hydrocarbons via steam reforming, partial oxidation and electrolysis of water are the major commercial hydrogen production technologies. However, these methods are not economically viable, ... -
Carbon Based Coatings for Metallic Bipolar Plates in PEM Fuel Cells
Husby, Håvard (Master thesis, 2013)Global warming and the climate changes are issues that concern everyone. The transition to other energy carriers than fossil fuels is a key barrier if we are to reduce our dependence on oil. Hydrogen is forecasted as the ... -
Carbon dioxide absorption into hydroxide and carbonate systems
Gondal, Shahla (Doktoravhandlinger ved NTNU, 1503-8181; 2014:265, Doctoral thesis, 2014)In the global warming scenario, a literature review on carbon dioxide capture technologies shows that CO2 capture by chemical absorption seems to be the immediately viable route for sustainable energy supply in near future. ... -
Carbon Dioxide Capture from Flue Gas by FSC (Fixed-Site-Carrier) Membranes: The Effect on Membrane Separation Properties of Casting Solution pH and Exposure to Contaminants
Leithe, Anna Elise (Master thesis, 2011)Polyvinyl amine (PVAm) Fixed-Site-Carrier (FSC) membranes prepared with various casting solution pH were developed for CO2 capture from flue gas. Among these membranes tested, the membranes prepared from casting solutions ... -
Carbon dioxide capture with carbonate systems

Carbon dioxide separation from flue gas by FSC (Fixed-Site-Carrier) membranes: Investigation on effect of polymer casting solution pH and process parameters on carbon dioxide separation at lab scale and pilot set-up scale
Katto, Aristides Robert (Master thesis, 2012)In this master thesis work, the fixed site carrier (FSC) polyvinylamine (PVAm) composite membranes were studied for their CO2 separation performance with respect to the pH of their casting solution. The study was done at ... -
Carbon formation phenomena and the initial stage of metal dusting corrosion –an experimental investigation
Gunawardana, P.V. Daham S. (Doktoravhandlinger ved NTNU, 1503-8181; 2014:27, Doctoral thesis, 2014)Metal dusting corrosion is high temperature degradation of metals and alloys into dust-like fine particles. It is often encountered in petrochemical industry, where metals and alloys extensively exposed to carbon containing ... -
Catalyst formulations for use in microstructured reactors for conversion of synthesis gas to liquids
Phan, Xuyen Kim (Doktoravhandlinger ved NTNU, 1503-8181; 2011:15, Doctoral thesis, 2011)Potential natural gas reserves in the world are more than 6000 trillion cubic feet. However, approximately 25% of these gas reserves are located offshore with no economic feasibility to be produced, transported and sold. ... -
Catalytic Dehydrogenation of Propane: Oxidative and Non-Oxidative Dehydrogenation of Propane
Herauville, Virginie Marie Therese (Master thesis, 2012)The dehydrogenation of propane has a great interest, due to a global growing demand in propene. This reaction needs a catalyst, high temperature and low propane partial pressure. During this work, platinum hydrotalcite-supported ... -
Catalytic Hydrodeoxygenation of Bio-oils with Supported MoP-Catalysts
Asphaug, Sindre (Master thesis, 2013)The goal of this thesis was to test the MoP catalysts which were made during autumn 2012, in a HDO reaction of phenol to benzene at a HDO rig. The catalysts were supported by Al2O3, SiO2, TiO2 and ZrO2, and they were ... -
Catalytic isomerization of light alkanes
Løften, Thomas (Doktoravhandlinger ved NTNU, 1503-8181; 2004:160, Doctoral thesis, 2004)In recent years the levels of sulfur and benzene in the gasoline pool have been reduced, and in the future there may also be new regulations on vapor pressure and the level of aromatics and olefins as well. The limitations ... -
