  1. 6. Evaluation of the new Power & Biomass to Liquid (PBtL) concept for production of biofuels from woody biomass

    Master-uppsats, KTH/Kemiteknik

    Författare :Robert Dahl; [2021]
    Nyckelord :PBtL; Fischer-Tropsch Synthesis; Biofuels; ASF product distribution; Aspen Plus; PBtL; Fischer-Tropsch syntes; Biobränslen; ASF produktfördelning; Aspen Plus;

    Sammanfattning : I den här rapporten utvärderas det nya konceptet Power & Biomass to Liquid (PBtL). PBtL är ett alternativ till den tidigare och mer etablerade Biomass to Liquid (BtL) processen. Med PBtL förbättras utbytet av kol jämfört med BtL genom att elektricitet läggs till i processen. LÄS MER

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Balaji Naik Sugali; [2021]
    Nyckelord :Ash dieback; coarse woody debris; dead wood volume; Dutch elm disease; forest reserve; Sweden; temperate forest; tree log; tree snag;

    Sammanfattning : Coarse Woody Debris (CWD) is a critical structural and functional component of all forest ecosystems and comprises non-living woody biomass, standing or lying, larger than 10 cm in diameter. This study provides the first inventory of coarse woody debris in the temperate broadleaf forest of Dalby Söderskog national park in southern Sweden. LÄS MER

  4. 8. Valorization of lignin for material applications

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Filippa Winkvist; [2021]
    Nyckelord :microwave-assisted extraction; lignin; LCC; PLA; Pine; mikrovågsassisterad extraktion; lignin; LCC; PLA; tall;

    Sammanfattning : Lignin är, med undantag för cellulosa, den av de naturliga polymererna det finns mest av på jorden och den ledande källan till fenolföreningar. De träväxterna som existerar idag, innehåller ca 30 % av just denna biopolymer. LÄS MER

  5. 9. Evaluation of the possibility of phytoremediation (using Salix) as a management tool for abandoned sites moderately contaminated with arsenic : a literature review

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Victor Akinwale; [2020]
    Nyckelord :phytostabilization; leaching; solubility and mobility; economic benefits;

    Sammanfattning : The presence of arsenic in soil and water has become an increasing problem in many countries around the world. The exposure of high concentration of arsenic in its inorganic form in natural environment such as soil and water makes it harmful to both humans, wildlife and plants. LÄS MER
