Initial stages of metal dusting corrosion
(Master thesis, 2015)Metal dusting is a disintegration phenomenon of metals and alloys into fine, dust-like particles. Metal dusting can be found in different reforming units in the petrochemical industry. As well as in reforming units, it can ... -
Initial Stages of Metal Dusting Corrosion - Surface and subsurface investigation using SEM, Raman spectroscopy, and STEM
(Master thesis, 2018)Metal dusting (MD) is a corrosion phenomenon that often occurs in industrial processes involving syngas. Carbon deposited on vessel walls gradually causes disintegration of the bulk metal. Because MD is related to carbon ... -
Initialization Methods for large Process Models
(Master thesis, 2019)Modellbygging er en viktig del av enhver modelldrevet forskning. Mange aspekter ved modellering er tidkrevende, hvorav en er initialiseringen når modellene blir store. Denne oppgaven presenterer implementeringen av en ... -

INJECTION OF SYNTHETIC PRODUCED WATER INTO POROUS MEDIA - A study of transport of dispersed components through simulated reservoir packs
(Master thesis, 2018)Produced water(PW) contributes to the largest volume byproduct from the oil production industry. The presence of hazardous chemicals makes the handling of PW an important and costly operation. Methods such as discharge ... -
Input transformation for linearization, decoupling and disturbance rejection with application to steam networks
(Peer reviewed; Journal article, 2021)Pressure-flow networks are inherently multivariable, coupled and nonlinear systems that are not straightforward handled by conventional PID controllers. In this work, we analyze the control problem for a steam distribution ... -
Insight into Size- and Metal-Dependent Activity and the Mechanism for Steam Methane Re-forming in Nanocatalysis
(Peer reviewed; Journal article, 2020)Systematic and in-depth understanding of size- and metal-dependent activity plays a pivotal role in nanocatalysis for rational design of highly efficient catalysts. Herein, we report an approach combining microkinetic ... -
Insights into Activated Carbon-Supported Platinum Catalysts for Base-Free Oxidation of Glycerol
(Journal article; Peer reviewed, 2016)Two kinds of activated carbon (AC)-supported Pt catalysts with similar particle sizes were respectively synthesized using the polyol method and incipient wetness impregnation method, and then tested for glycerol oxidation ... -
Insights into Growth Mechanism, Control of Particle Size and Particle Size Distribution of Silica Coated Iron Oxide Nanoparticles

Insights into hydrogen transport behavior on perovskite surfaces: Transition from the Grotthuss mechanism to the “vehicle” mechanism
(Journal article; Peer reviewed, 2019)Hydrogen transport on transition-metal oxides is a shared process in many important physical and chemical changes of interest. In this work, DFT + U calculations have been carried out to explore the mechanism for hydrogen ... -
Insights into size-dependent activity and active sites of Au nanoparticles supported on TS-1 for propene epoxidation with H2 and O2
(Journal article; Peer reviewed, 2014)Propene epoxidation with H2/O2 is a typical structure-sensitive reaction. For a given support containing tetra-coordinated Ti species such as TS-1, the catalytic activity is greatly influenced by supported Au nanoparticle ... -
Insights into the synergy between recyclable magnetic Fe 3 O 4 and zeolite for catalytic aquathermolysis of heavy crude oil
(Journal article; Peer reviewed, 2018)Understanding the synergy between metal and zeolite for catalytic aquathermolysis harbours tremendous scientific and industrial importance. Herein, HZSM-5 is used as a model zeolite due to uniform physico-chemical structure, ... -
Integrated Experimental and computational studies on plasmonic nanoparticles
(Doctoral theses at NTNU;2023:150, Doctoral thesis, 2023)A typical diagnosis of a medical condition takes time, and the start of therapy to cure or manage the condition can take even longer. This can be changed by using nanoparticles that are personalised for biomedical applications. ... -
An integrated materials approach to ultrapermeable and ultraselective CO2 polymer membranes
(Peer reviewed; Journal article, 2022)A challenge in the design of polymeric membranes for gas separation is the tradeoff between permeability, or how fast gases can flow through the membrane, and selectivity, the ability to separate one gas from another. In ... -
Integration of Renewable Production of Hydrogen in Current Biomass-to-Liquid Biofuels Production Systems
(Master thesis, 2017)This report focuses on the production of hydrocarbons in a biomass to liquid (BtL) process with integration of hydrogen production. The hydrogen will be produced from high temperature electrolysis of steam utilizing excess ... -
