  1. 1. Microwave Heat Treatment of Black Liquor for the Degradation of Hemicellulose

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Maja Rydgård; [2020]
    Nyckelord :lignin; biofuel; black liquor; heat treatment; microwave heating; chemical engineering; kemiteknik; Technology and Engineering; Chemistry;

    Sammanfattning : The largest use of fossil petroleum is the production of fuels. Hence, finding sustainable alter-natives is an important step to reduce the emissions of greenhouse gases. One such alternative is to produce fuel from biomass, such as waste products from agriculture and the forest indus-try. LÄS MER

  2. 2. Mapping and characterisation of surface damage and wear mechanisms in gun barrels : Gun barrels exposed to cyclic thermo-mechanical loading

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Martin Perkovic; [2020]
    Nyckelord :Wear; erosion; sliding wear; gun barrel; characterisation;

    Sammanfattning : Gun barrels are an important component in advanced defence systems. The gun barrels are used for direct and indirect fire and the material of the gun barrel is exposed to great strains and high temperatures. This sets high demands on the material of the gun barrel. During firing the gun barrel can be damaged. LÄS MER

  3. 3. Process development for H13 tool steel powder in binder jet process

    M1-uppsats, Högskolan i Gävle/Maskinteknik

    Författare :George Persson; [2020]
    Nyckelord :Additive manufacturing; H13; toolsteel; binder jetting; processutveckling.;

    Sammanfattning : Additive manufacturing brings versatility and new degree of freedom for part design and manufacturing possibilities. Binder jetting is powder bed printing technique that does not require direct energy transfer rather binding powder metal particles through mechanical entanglement by use of the organic binder.

  4. 4. 3D-Printed Injection Molds

    Master-uppsats, Lunds universitet/Produktutveckling

    Författare :David Helin; Kristoffer Palmér; [2020]
    Nyckelord :Product development; Prototyping; Additive manufacturing; Injection molding; 3D-Printing; Technology and Engineering;

    Sammanfattning : This master thesis describes the development process of a prototyping process. It was carried out in collaboration with Axis Communications. When creating plastic prototypes, development engineers usually have two options, 3D-printing or injection molding using a soft tool. LÄS MER

  5. 5. Introducing a central receiver system for industrial high-temperature process heat applications : A techno-economic case study of a large-scale CST plant system in a South African manganese sinter plant

    Master-uppsats, KTH/Kraft- och värmeteknologi; KTH/Kraft- och värmeteknologi

    Författare :Maria Hallberg; Elin Hallme; [2019]
    Nyckelord :Solar energy; concentrating solar thermal; CST; central receiver system; CR; HelioPod; high-temperature process heat; manganese; business case; Solenergi; koncentrerad termisk solvärme; CST; soltorn; HelioPod; högtempererad processvärme; mangan; affärsmodell;

    Sammanfattning : The objective of this thesis was to investigate the potential for introducing a concentrating solar thermal (CST) central receiver plant system based on flexible heliostats - HelioPods - to provide high-temperature process heat in industrial applications. A CST plant system was designed in MATLAB, optically simulated for three design days in the ray-tracing software Tonatiuh and further analyzed in MATLAB by interpolating the results for each hour of the year.
