Biopolymers assisted preparation of iron based fischer-tropsch catalysts
Harneshaug, Marit Liebe (Master thesis, 2018) -
Capture of Carbon Dioxide in Lamellar Phase Liquid Crystals
Øyen, Marita (Master thesis, 2018)One of the most important environmental concerns the earth faces today is the release of greenhouse gases and other gases that accumulate in the atmosphere. Among these gases, carbon dioxide is one of the most abundant ... -
Carbon dioxide absorption with non-porous hollow fiber membrane contactors - Module fabrication and characterisation
Andreassen, Vilde Elin (Master thesis, 2018)Carbon capture and storage (CCS) is recognised as one of the key technologies to reduce greenhouse gas emissions from industrial plants. Currently, the most established technology is chemical absorption with amines, but ... -
Catalytic Methane Abatement for Natural Gas Engines
Granlund, Helene Marie Eng (Master thesis, 2018)To reduce the greenhouse emissions it is proposed to use natural gas vehicles in the marine sector, instead of conventional vehicles using heavy fuel oil. Use of natural gas will reduce NOx, SOx and CO2 emissions, and will ... -
Catalytic upgrading of Biomass derived Oxygenate on Copper based Catalysts.
Hansen, Stine (Master thesis, 2017)Renewable production of propylene glycol (PG) has great interest. This can be produced from biomass derived chemicals instead of today s production, where PG is conventionally produced from petroleum derived chemicals. Acetol, ... -
CFD Simulation of Concentration Sensor
Gensor, Martin (Master thesis, 2016)This thesis deals with the CFD modelling of a NaCl concentration sensor, specifically its pressure drop, but also velocity and pressure profile. The main goal of the work is twofold: firstly, to confirm whether the simulations ... -
Cobalt/Manganese Oxide Nanoparticles for Enhanced Olefin Production in Fischer-Tropsch
Straume, Hanne Marie (Master thesis, 2015)The Fischer-Tropsch process for the production of fuels and chemicals from alternative carbon containing feedstocks have become of increasing interest in recent years. Special attention towards the the production of light ... -
Crystallization behavior of an X-Ray Contrast Agent Intermediate at high Supersaturations and Temperatures
Bakke, Bjørnar (Master thesis, 2016)This project comprises studies of crystallization of an aromatic amine, which is an intermediate in the production of the X-ray contrast agent Iohexol at GE Healthcare Lindesnes Site. Crystallizations from highly supersaturated ... -
Cu-Promoted Fe-Based Catalyst for Biomass-Derived Synthesis Gas for the Fischer-Tropsch Synthesis
Jensen, Lise Saue (Master thesis, 2015)Four alumina supported iron-based catalysts were prepared by incipient wetness impregnation. The Fe loading was kept constant at 15 wt.%, and the Cu loading was varied between 0-5 wt.. The catalyst samples were characterized ... -
Destabilization of crude oil emulsions by combining chemicals and electric fields
Jakobsen, Angela (Master thesis, 2015)In today s oil industry the increasing scarcity of the conventional oil is inevitable and pushes the oil companies towards the exploitation of unconventional oils such as oil- sands, heavy oil and extra heavy oil. During ... -
Development of Kraft Lignin and Coating Technique to Prepare Coated Urea Fertilizers with Increased Nutrient Use Efficiency
Xu, Xueyan (Master thesis, 2017)Coating urea to prepare controlled release N-fertilizer has been considered as an effective way to increase its nutrient use efficiency, thus reduce its waste and the consequent harmful environmental impacts. Inorganic ... -
Development of Visible Light-Responsive Photocatalysts for Hydrogen Production from Glycerol
Apan, Shawn Christopher (Master thesis, 2016)Different catalyst preparation methods were performed. In the case of TiO2, the cocatalyst was deposited on commercial TiO2-P25 by wet impregnation. Cu-loaded and Pt-loaded TiO2 was achieved by calcination in static air ... -
Direct Non-Oxidative Conversion of Methane to C2 Hydrocarbons, Aromatics and Hydrogen
Bodnar, Matus (Master thesis, 2017)Catalytic activity of Fe/HZSM-5 and Mo/HZSM-5 during methane dehydroaromatization was investigated. The catalysts were prepared by wet impregnation method, calcinated in air flow, tested in laboratory reactor and characterized ... -
Dynamic modeling and optimalization of the cheese making procedure
Kjellstrøm, Tomas Tungen (Master thesis, 2017)This thesis has successfully derived an dynamic model based on analytic solutions for production of semi-hard cheeses on the basis of raw milk from the cattle breed Norwegian red. The main emphasis has been to create a ... -
Dynamic modelling of a Hydrocracker
Leirpoll, Anders Tyseng (Master thesis, 2016)Different types of petroleum refining processes were considered to be modelled in the Kongsberg dynamic modelling software K-Spice. Multiple oil and gas processing units exist in the model library, which begs the question ... -
