One-pot conversion of biomass to chemicals
(Master thesis, 2017)One-pot conversion of biomass to diols can be a simple and fast alternative to other methods of biomass conversion. The catalyst for this conversion is required to be bifunctional, catalysing both hydrogenation and retro-aldol ... -
One-pot Conversion of Biomass to Chemicals on Ni-Cu/ZnO Based Catalysts
(Master thesis, 2015)Optimization of the one-pot hydrothermal reaction of cellulose to polyols have been investigated. Ni-Cu-ZnO catalysts supported by carbon nanotubes (CNT) with varying nickel (Ni) and copper (Cu) mole ratio was synthesized ... -
Optimal operation of energy storage in buildings - Use of hot water systems
(Master thesis, 2013)The purpose of this study is to maximize the potential which lies in domestic hot water heaters. Today the temperature function in the hot water tank is constant throughout the day and the hot water demand is met by an ... -
Performance Investigation of Membranes Suitable for Osmotic Membrane Pressure Actuators
(Master thesis, 2014)Polybenzimidazole (PBI) membrane performance having hydrocarbons mixed with the feed water was investigated. Forward osmosis (FO) and pressure retarded osmosis (PRO) experiments were performed with different ratios of ... -
Polyethyleneimine-coated magnetic iron oxide nanoparticles for improvement of flow assurance
(Master thesis, 2017)This thesis aims to gain further insight into how the naphthenic acids (NA), which cause different problems with respect to flow assurance, can be removed from the water phase. The main objective has been to test how ... -
Polymeric Hydrogels for Drug Delivery
(Master thesis, 2014)Targeting specific drugs to a diseased site is widely studied both in vitro and in vivo, but very few systems have made entry into the clinical market. The systems today cause unwanted side effects due to the lack of ... -
Properties and application of PdCu membranes for hydrogen separation.
(Master thesis, 2014)Hydrogen is one of the most important chemicals used in the industry today. The energy in hydrogen molecules can be converted into electric energy in fuel cells, and hydrogen is thus considered an energy carrier for the ... -
Reactive Distillation of Biodiesel: Modelling and Optimal Operation
(Master thesis, 2013)This thesis modifies an already existing dynamic Matlab Simulink model to correlate with a Hysys model from a similar research. The models are concerned with the reactive distillation for production of biodiesel from ... -
Risk for mould growth in insulation materials
(Master thesis, 2014)The aim of this project has been to evaluate what effect different types of fire retardant additives have on mold growth in cellulose insulations. The cellulose insulation materials used have been prepared from two different ... -
SiC supported Co catalysts for the Fischer-Tropsch synthesis
(Master thesis, 2012)With rising crude oil prices and outlook of declining crude oil production, conversion of natural gas into liquid fuels is gaining worldwide interest. Fischer-Tropsch synthesis is an important tool in achieving this ... -
Stabilization of two-phase flow in risers from reservoirs - Robust anti-slug control strategies
(Master thesis, 2011)This thesis is an experimental study of robust ant-slug control strategies for riser systems. The main objective of this thesis was to develop a robust anti- slug control scheme to increase the stability of riser systems. ... -
Study on initial stage of metal dusting corrosive on Inconel 601 and Incoloy 800
(Master thesis, 2017)Metal dusting is a corrosive phenomenon of metals or alloys into fine, dust-like particles. It can be found in many industrial units or processes, such as petrochemical industry. Metal dusting is initiated by unwanted ... -
Synthesis and Characterisation of Co-based Fischer-Tropsch Catalysts and Supports, using hydrothermal and chemical attrition Method - The magnesium moderation Effect
(Master thesis, 2011)Magnesium modification at different calcination temperatures of γ-alumina supports for cobalt Fischer-Tropsch catalysts was investigated. Support modification and catalyst preparation were performed by applying the incipient ... -
Synthesis of Fischer-Tropsch Catalysts in an Autoclave System
(Master thesis, 2012)12- or 18 wt.% cobalt and 0.5 wt.% rhenium was impregnated on nickel-aluminate spinel support supplied by Statoil R&D. The catalysts were dried in an autoclave continuous stirred tank reactor with different reactor parameters. ... -
Thermodynamic Analysis of Heat and Mass Transfer Using Entropy Production Formalism
(Master thesis, 2015)The understanding of irreversible phenomena in the world around us is of great importance -- not only for the intrinsic value of such understanding, but also for the industrial applications and technological benefits such ... -
Vapour-liquid equilibrium in the monoethylene glycol - methane system at elevated pressures
(Master thesis, 2012)A range of different chemicals are used in natural gas processing. The systems operate in closed loops, but a small amount of the chemicals are lost due to the solubility of the chemical in the gas phase. This leads to ...
