  1. 1. Electrolytic Reduction of Iron Oxides in Molten Salt with a Mineralogical Investigation of Magnetite Ore of Tapuli

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Elina Fernö; [2023]
    Keywords : Iron reduction; trace element analysis on magnetite ore; molten salt electrolysis; sodium hydroxide electrolyte; NaOH; greenhouse gas; carbon dioxide; CO2; green ironmaking; Järnreduktion; spårelementanalys på magnetitmalm; smältelektrolys; elektrolys i natriumhydroxid; NaOH; elektrolyt; växthusgas; koldioxid; CO2; grön järnframställning;

    Abstract : This master's thesis covers an investigation of the reduction behavior of different iron oxides when electrolytically reduced with molten salt electrolysis (MSE). The tested iron oxides were wüstite (FeO), hematite (Fe2O3), magnetite (Fe3O4) and magnetite ore concentrate from the Tapuli deposit in Pajala, Norrbotten, Sweden. READ MORE

  2. 2. How the Choice of Primary Treatment Affects the Biogas Potential of Primary Sludge

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Fanny Blom; [2022]
    Keywords : wastewater treatment; primary treatment; biogas potential; primary settling treatment; rotating belt filter; chemically enhanced primary treatment; environmental engineering; water resources engineering; Technology and Engineering;

    Abstract : The global heating has resulted in rising temperatures and more extreme weather conditions around the world. In combination with increasing energy demands, this has led to an increasing demand of renewable energy. One option is utilizing the wastewater to produce biogas. There-fore, wastewater can be seen as a resource rather than waste. READ MORE

  3. 3. Oxidation of cellulose to favour its dissolution in alkaline aqueous solution before regeneration into textile yarn

    University essay from KTH/Kemiteknik

    Author : Martin Orpiszak; [2021]
    Keywords : Cellulose; periodate oxidation; dissolution; regeneration; textile yarn; cellulosa; natriumperjodat oxidation; upplösning; regenerering; textilgarn;

    Abstract : Detta examensarbete är en del av CelluFil-projektet och syftar till att optimera förhållandena för upplösning av cellulosa i vattenlösning av natriumhydroxid följd av regenering i form av ett garn. Tidigare arbeten har visa tatt cellulosa kan lösas i vattenlösning vid -10°C, men sådana förhållanden är inte tillämpliga i industriell skala. READ MORE

  4. 4. Skogsprodukter som idisslarfoder vid bristsituationer med fokus på mjölkkor

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Ida Milton; [2020]
    Keywords : skogsprodukter; skogsråvaror; smältbarhet; grovfoder; idisslare; mjölkkor; mjölkavkastning; förbehandling; processteknik;

    Abstract : Träd innehåller cellulosa och hemicellulosa, vilket idisslare kan bryta ned och utvinna energi ifrån. Skogsprodukter/skogsråvaror så som träflis, spån, bark och pappersmassa har därför god potential till att fungera som grovfoder för idisslare. READ MORE

  5. 5. The feasibility of using macroalgae from anaerobic digestion as fertilizer in Grenada : A literature study of the potential use of residue as fertilizer in Grenada, and a complementary laboratory study to evaluate the biogas potential

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Anna Sterley; Daniel Thörnkvist; [2020]
    Keywords : Methane; Carbon dioxide; Heavy metals; Sodium hydroxide; Normal cubic meter; Renewable energy; Saccharina latissima; Small Island Developing States; Total solids; Volatile substance; Wet weight; Biokemisk metanpotential; Metan; Koldioxid; Tungmetaller; Natriumhydroxid; Normalkubikmeter; Förnybar energi; Saccharina latissima; Small Island Developing States; Torrsubstans; Organiskt material; Våtvikt;

    Abstract : Coastal areas in Grenada and the Caribbean are experiencing an abundance of stranded macroalgae. Climate change and eutrophication are probable causes of this inconvenience. This leads to logistic and economic dilemmas for the Caribbean societies. READ MORE
