  1. 1. Reactivity increasement of prehydrolysis kraft pulp from Acacia crassicarpa and Eucalyptus hybrids

    University essay from KTH/Träkemi och massateknologi

    Author : Edward Tandy; [2022]
    Keywords : Acacia crassicarpa; Eucalyptus hybrids; Pentosan removal; Pulp yield; Prehydrolysis kraft pulp; Reactivity; Acacia crassicarpa; Eucalyptushybrider; Förhydrolyserad kraftmassa; Massautbyte; Pentosan; Reaktivitet;

    Abstract : Syftet med detta examensarbete var att öka reaktiviteten hos förhydrolyserad kraftmassa genom att använda tidigare förhydrolysat och svavelsyra under förhydrolysen. Först bestämdes den kemiska sammansättningen av två olika vedråvaror (Acacia crassicarpa och Eucalyptushybrider) för att observera och korrelera med förhydrolysprocessen. READ MORE

  3. 2. Tillväxt hos inhemska trädslag i Borneo : en jämförelse av 34 arter inom ett återbeskogningsförsök

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Filip Bonnerup; Simon Vesterlund; [2022]
    Keywords : återbeskogning; inhemska arter; kolinlagring; tropisk; Borneo;

    Abstract : Degradation of tropical forests have had a major negative impact on biodiversity in these speciesrich systems, as well as lowering carbon sequestration. This results in these systems losing their potential to bind parts of the carbon dioxide that is causing the ongoing climate change. READ MORE

  4. 3. Effects of afforestation of agricultural land on the water balance in Ethiopian Highlands

    University essay from SLU/Dept. of Soil and Environment

    Author : Mwala Silumesi; [2022]
    Keywords : acacia decurrens; aquaCrop Mode; afforestation; water balance; teff;

    Abstract : In this study, I examined how land use change affects the partitioning of water and how soil-plant interactions are impacted by yearly rainfall at a stand scale. Even though many studies have been conducted to evaluate the extent of land use change and the economic impacts, few have attempted to study the rapid farmer-driven afforestation with Acacia decurrens and also disaggregated dry, normal and dry seasons at stand scale.

  5. 4. Technical Lignin Characterization of Acacia crassicarpa and Eucalyptus Hybrids

    University essay from KTH/Träkemi och massateknologi

    Author : Lutfi Difi Rosta; [2021]
    Keywords : Lignin; Acacia crassicarpa; Eucalyptus Hybrids; kraft cooking; kraft dissolving pulp cooking; Lignin; Acacia crassicarpa; Eucalyptus Hybrids; kraftkokning; kraftupplösning av massa;

    Abstract : Lignin är en av de vanligaste naturliga råvarorna på jorden och finns mestadels i trä. Nuförtiden är valoriseringen av lignin en av processutvecklingarna för teknologier inom massa- och pappersindustrin. Denna utveckling syftar till att öka värdet av lignin. READ MORE

  6. 5. Effects of afforestation and crop systems on the water balance in the highlands of Ethiopia

    University essay from SLU/Dept. of Soil and Environment

    Author : Rebecca Naomi Ter Borg; [2020]
    Keywords : Acacia decurrens; landscape water balance; sediment yield; soil and water conservation; SWAT modelling; water balance partitioning;

    Abstract : In the Upper Blue Nile Basin land use is rapidly changing due to agricultural development and intensification with potential effects on the water availability both up- and downstream. This study is aimed to explore the impact of agricultural land use change on a landscape water balance. READ MORE
