  1. 6. Chemical Modification of Cellulose Nanocrystals: Creating a Novel Toolbox Utilising the Overlooked Sulphate Surface Groups

    Författare :Karin Sjövold; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Composites; Scale-up; Dialkylamines; Cellulose nanocrystals; Azetidinium salts; Chemical modification; Thermal stability;

    Sammanfattning : The move towards a bio-based economy has created an increasing demand for renewable, sustainably produced materials. For future generations, it is crucial to develop economically, socially and environmentally sustainable materials and processes. LÄS MER

  3. 7. Pressurized entrained-flow high temperature black liquor gasification : CFD based reactor scale-up method and spray burner characterization

    Författare :Magnus Marklund; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : Black liquor is an important by-product in the chemical kraft pulping process, which provides the paper mill with pulp. Due to both economical and environmental protection driving forces it is important to recover the pulping chemicals and energy contained in the black liquor. LÄS MER

  4. 8. Absorption Based Systems for Co-removal of Nitrogen Oxides and Sulfur Oxides from Flue Gases

    Författare :Jakob Johansson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SOx; absorption; ClO2; sulfite oxidation; gas-phase oxidation; NOx; Emissions control; scale-up;

    Sammanfattning : Enhanced control of nitrogen and sulfur emissions, found in many of industrial processes, is anticipated for decades to come. Stricter emission regulations require new technologies adapted to the new conditions at reasonable cost. LÄS MER

  5. 9. Upscaling and Evaluation of Absorption Based Systems for Co-removal of NOx and SOx from Flue Gases

    Författare :Jakob Johansson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; absorption; gas-phase oxidation; scale-up; Emissions control; SOx; NOx; ClO2;

    Sammanfattning : As long as combustion remains a vital part of the energy system, the removal of nitrogen oxides (NOx) will be a challenge that will need to be addressed. In addition, emissions of sulfur oxides (SOx) will be a problem as long as fuels such as coal and oil are used, as is envisaged in every road map suggested by the Intergovernmental Panel on Climate Change (IPPC).

  7. 10. Entrepreneurial Ecosystems in Life Science Industry : A study of start-ups, scale ups and resilience of Entrepreneurial Ecosystems

    Författare :Janna Alvedalen; Innovationsteknik; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Entrepreneurial ecosystems; Life Sciences; Sweden; US; scale up; high-growth firms; Resilience; place leadership; social capital; entrepreneurship; closure of large firm; productive entrepreneurship;

    Sammanfattning : The Entrepreneurial Ecosystem (EE) literature has presented itself as promising in recent years, as it adopts a systemic network approach on entrepreneurship. Despite its popularity, scholars have also raised some serious concerns, showing it is yet a rather underdeveloped concept. LÄS MER
