Safety aspects of maritime hydrogen fuel from local sorption-enhanced ethanol steam reforming
Hansen, Eirik Søreide (Master thesis, 2020)Damp reformering av etanol med integrert CO2-fangst, såkalt sorption-enhanced ethanol steam reforming (SEESR), har potensiale til å effektivt konvertere etanol til hydrogen. I denne masteroppgaven vurderes sikkerhetsaspekter ... -
Sorbents for Sulfur Removal From Biomass-derived Syngas
Stavnes, Siri (Master thesis, 2018)The rising concern of global warming and emission of greenhouse gases have increased the demand for sustainable resources. Biomass is carbon neutral and a renewable energy source, thus a promising alternative to produce ... -
Sorption of hydrogen chloride on solid sorbents
Paereli, Sergiu (Master thesis, 2015)The problem of the refinery streams contamination with hydrogen chloride has increased. Catalytic reforming is one of the major processes causing the contamination of such petroleum fractions as LPG and naphtha with this ... -
Sorption-enhanced Fischer-Tropsch synthesis – Effect of water removal
Gavrilovic, Ljubisa; Kazi, Saima Sultana; Oliveira, Antonio; Encinas, Oscar Luis Ivanez; Blekkan, Edd Anders (Peer reviewed; Journal article, 2024)The Sorption-Enhanced Fischer-Tropsch synthesis (SEFTS), with water removal by means of a solid sorbent, has been demonstrated for the first time experimentally. Commercial water sorbents (Zeolites type 13X and 4 A) were ... -
Staging and path optimization of Fischer-Tropsch synthesis
Pandey, Umesh; Putta, Koteswara Rao; Rout, Kumar Ranjan; Blekkan, Edd Anders; Rytter, Erling; Hillestad, Magne (Peer reviewed; Journal article, 2022)Optimization of once-through three-stage Fischer-Tropsch (FT) synthesis using path optimization is performed in this study to identify optimal structure and strategies in multi-stage FT synthesis design. The study also ... -
Steady-State and Transient Kinetic Investigations of the Oxidation of NO over Pt/SiO2
Mawanga, Moses; Yang, Jia; Blekkan, Edd Anders (Journal article; Peer reviewed, 2024)The reaction mechanism of the oxidation of NO under conditions of high NO concentration over a 2 wt% Pt/SiO2 was studied using both kinetic and transient isotopic tracing experiments. The reaction mechanism was found to ... -
Structure-performance relationships on Co based Fischer–Tropsch synthesis catalysts: The more defect free the better
Tsakoumis, Nikolaos; Patanou, Eleni; Lögdberg, Sara; Johnsen, Rune; Myrstad, Rune; Van Beek, Wouter; Rytter, Erling; Blekkan, Edd Anders (Journal article; Peer reviewed, 2018)Understanding and utilizing structure–performance relationships in catalytic nanomaterials is the epitome of catalysis science. Knowledge at the atomic level can potentially allow rational design of more selective and ... -
Synthesis of high-temperature solid sorbents for CO2 capture
Lilleng, Ane Sofie (Master thesis, 2018)The use of fossil fuels have escalated since the first industrial applications at the mid 19th century with a consequence of increased emissions of carbon dioxide and other green house gases. As a result, the global climate ... -
The effect of aerosol-deposited ash components on a cobalt-based Fischer–Tropsch catalyst
Gavrilovic, Ljubisa; Brandin, Jan; Holmen, Anders; Venvik, Hilde Johnsen; Myrstad, Rune; Blekkan, Edd Anders (Journal article; Peer reviewed, 2019)The effect of ash salts on Co-based Fisher–Tropsch catalysts was studied using an aerosol deposition technique. The major elements in the ash were found to be K, S and Cl. The ash was deposited on a calcined catalyst as ... -
