  1. 1. Modified lignin as replacement of carbon black in elastomers- For the development of sustainable tyre technology : The substitution of carbon black with modified lignin- Green tyre technology

    Master-uppsats, Karlstads universitet/Avdelningen för kemiteknik

    Författare :Mostafa Ahmed Ismail; [2020]
    Nyckelord :lignin; tyre rubber; elastomeric materials; esterfication;

    Sammanfattning : Due to its large flexibility, low-price, large availability, and properties lignin is seen as an important compound with a wide range of applications. The increasing demand of fossil-based rubber materials is causing a serious threat to the environment and it is contributing to plastic- and marine pollution, ozone depletion and carbon dioxide emission (CO2) [1,2].

  3. 2. Biodrivmedel från lignin

    Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Darius Kvainauskas; Martin Johansson; [2018]
    Nyckelord :;

    Sammanfattning : Lignin är en molekyl som finns i alla växter och kan användas för att framställa nya generationens biodrivmedel. Ligninbaserade biodrivmedel är bra från en miljöaspekt för att det minskar växthuseffekten, men också för att utvinningen av svartlut kan effektivisera tillverkning av pappersmassa. LÄS MER

  4. 3. Influence of metal ions on lignin-based carbon fiber quality

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Industriell miljö- och processteknik

    Författare :Sofia Andersson; [2017]
    Nyckelord :Carbon fiber; lignin; kraft lignin; cellulose; impregnation; LignoBoost; metal; ash; inorganic; black liquor; morfology; tensile testing; dry-jet wet spinning;

    Sammanfattning : Carbon fiber is a lightweight, versatile material with many current and potential applications. To be able to expand the market for carbon fiber composites in other areas than special applications the production costs must be reduced. LÄS MER

  5. 4. Development of Kraft Lignin and Coating Technique to Prepare Coated Urea Fertilisers with Increased Nutrient Use Efficiency

    Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :Xueyan Xu; [2017]
    Nyckelord :fertilizer coating; lignin; modified lignin; polylactide; slow release; ytbeläggning för gödningsmedel; lignin; modifierad lignin; polylaktid; kontrollerad frisättning;

    Sammanfattning : Coating urea to prepare controlled release N-fertilizer has been considered as an effective way to increase its nutrient use efficiency, thus reduce its waste and the consequent harmful environmental impacts. Inorganic sulphur and synthetic polymers have been used in the industry as coating materials together with utilization of various types of expensive coating equipment which commonly requires also complicated technical setup and controls.

  7. 5. De-polymerization and Purification of Kraft Lignin Utilizing the Liquid-Lignin Phase

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Martin Sundin; [2017]
    Nyckelord :ALPHA; SLRP; Liquid-Lignin; Lignin; Technology and Engineering;

    Sammanfattning : The effects of global warming are apparent and the work towards a sustainable future is underway. In order to reduce the environmental impact caused by the transportation sector, a transition from fossil fuels to those based on renewable resources are important. Using agricultural land to produce raw materials, e.g. LÄS MER
