  1. 21. Performance Analysis of Environmentally Adaptable Grease in Large open gears

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Victor Ogunmoye; [2022]
    Keywords : Grease; Large open gears; tribology; lubrication; wear; friction; Twin disc; Material surface;

    Abstract : Environmentally adaptable grease (EAG) lubricants are essential in applications with loss lubrication due to their biodegradable nature. This is because the lubricants could be expelled into the environment during usage in some applications e.g., marine and mining applications. READ MORE

  3. 22. Continuous Hydrothermal Co-liquefaction of Biomass : An experimental study on the effects of fuel mixing on the composition and yield of biocrude and hydrochar

    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Author : Simon Fridolfsson; [2022]
    Keywords : HTL; TGA; SEM EDS; Co-liquefaction effects; GROT; Kraft lignin; Microalgae;

    Abstract : An experimental study on the effect of fuel mixing on the products resulting from hydrothermal liquefaction (HTL) was conducted. The feedstocks used were kraft lignin (KL), GROT (GT) and microalgae cultivated in wastewater (MA). Three sets of mixtures were prepared, each containing two types of feedstocks with a 1:1 ratio: KLGT, MAKL, and MAGT. READ MORE

  4. 23. The Fe-oxides (mineralogical, chemical, and textural) variation in the Leveäniemi deposit using micro-analytical tools for unraveling of primary features and metamorphic recrystallisation

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

    Author : Adrian Larsson; [2022]
    Keywords : Leveäniemi; Magnetite; Hematite; Iron oxides; Iron oxide apatite;

    Abstract : The Leveäniemi iron oxide apatite (IOA) deposit, mined by LKAB, is located in Norrbotten, northern Sweden. The deposit has a partially more complex mineralogy than the neighbouring and more famous IOA deposits of Kiirunavaara and Malmberget. READ MORE

  5. 24. Techniques for characterization and quantification analysis of foulant deposition in Alfa Laval’s high-speed separators : A literature study

    University essay from

    Author : Mwansa Benaya; Henrik Dahlén; Emil Axelsson; Cassandra Liljekvist; Maja Nordell; [2022]
    Keywords : Dairy foulant; Marine foulant; Characterization; Quantification; Stainless steel; surface; analysis;

    Abstract : Alfa Laval is a global company that provides solutions, products, and services for industry, such as high-speed separators for marine and food-application. Foulant deposition on the stainless-steel surfaces of Alfa Laval’s high-speed separators has shown to result in lowering of the separation efficiency. READ MORE

  6. 25. Effect of ash on catalytic activity for passive regeneration of catalytic diesel particulate filter : Evaluation of ash deposition by laboratory ageing

    University essay from KTH/Kemiteknik

    Author : Gisela Engström; [2022]
    Keywords : Diesel Particulate Filter; Ash deposition; Laboratory Ageing; Catalytic Activity; Passive regeneration;

    Abstract : Askackumulering i dieselpartikelfilter är ett välkänt problem som resulterar i ett förhöjt mottryck och påverkad prestanda hos fordonet. Däremot ges sällan uppmärksamhet åt filtrets katalytiska aktivitet och hur det påverkas vid förekomst av avgasföroreningar. READ MORE
