    Sammanfattning : This paper discusses the potential of gasoline, ethanol and methanol ternary blend as an alternative passenger car fuel in Sweden. Sweden has set various targets aimed to reduce its GHG emissions and to increase the share of renewables in the transportation sector. LÄS MER

  4. 18. Raising the efficiency of black liquor lignin extraction

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Konrad Nilsson; [2017]
    Nyckelord :Chemical Engineering; Kemiteknik; Lignin; Black Liquor; Technology and Engineering;

    Sammanfattning : The aim of this report was to study possibilities of making the process of extracting lignin from black liquor at pulp and paper mills more efficient in the form of a literature study. Lignin is a commodity that is likely to become more valuable in the future due to work being done by a number of companies in utilizing it as for example a base for the production of renewable fuels and carbon fibre.

  5. 19. Impact of hardwood black liquor addition on the chemical and physical properties of kraftliner - a lab study

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

    Författare :Fredrika Sundvall; [2017]
    Nyckelord :Hardwood black liquor; Xylan; Kraft pulping; Black liquor.;

    Sammanfattning : Kraft pulping, also known as sulphate pulping is a complex process where the wood components are liberated from each other facilitated by chemical reactions. During the pulping process some dissolved and degraded compounds end up together with the spent cooking chemicals in the black liquor. LÄS MER

  7. 20. Elektrobränsle via svartlutsförgasning : Teknoekonomisk analys av implementering av elektrolysör i biometanolproduktion

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Joel Weddig; [2017]
    Nyckelord :Electrofuels; Gasification; Methanol; Black liquor; Electrolyzer; Biomass; Elektrobränsle; Förgasning; Metanol; Svartlut; Elektrolysör; Biomassa;

    Sammanfattning : Med mer och billigare förnybar, intermittent el på marknaden har intresset för elektrobränsle ökat. I denna studie utvärderas tekno-ekonomiskt om elektrobränslekoncept kan vara fördelaktigt att implementera i en förgasningsanläggning för svartlut med nedströms metanolsyntes. LÄS MER
