   Sammanfattning : Reliable energy supply is a major concern and crucial for development of the global society. To address the dependency on fossil fuel and the negative effects of this reliance on climate, there is a need for a transition to cleaner sources. An attractive solution for replacing fossil-based products is renewable substitutes produced from biomass. LÄS MER

3. 17. Gasification-based Biorefinery for Mechanical Pulp Mills

   Författare :Jie He; Per Engstrand; Wennan Zhang; Olof Björkqvist; Christoph Pfeifer; Mittuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gasification; Mechanical Pulping; Biofuels; Power Generation; Biomass Residues; ASPEN Plus;

   Sammanfattning : The modern concept of “biorefinery” is dominantly based on chemical pulp mills to create more value than cellulose pulp fibres, and energy from the dissolved lignins and hemicelluloses. This concept is characterized by the conversion of biomass into various bio-based products. LÄS MER

5. 19. Pyrolysis profiles and global kinetics of tropical biomass : coconut and cashew nut shells

   Författare :Alberto Júlio Tsamba; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermogravimetry; cashew nut cocnut shells; pyrolysis; kinetics; Other materials science; Övrig teknisk materialvetenskap;

   Sammanfattning : Biomass has been recognised as renewable and environmentally friendly source of energy since decades. Tropical biomasses which are available in large quantities as residues in Latin America, Africa and Asia, have high energy potential for exploitation through thermochemical conversion process, as pyrolysis, gasification or combustion.

7. 20. Biomass conversion through syngas-based biorefineries : thermochemical process integration opportunities

   Författare :Katarina Åberg; Anders Nordin; Linda Pommer; Erik Dahlquist; Umeå universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomass; biorefinery; thermochemical conversion; torrefaction; slow pyrolysis; gasification; process integration; carbon negativity;

   Sammanfattning : The replacement of fossil resources through renewable alternatives is one way to mitigate global climate change. Biomass is the only renewable source of carbon available for replacing oil as a refining feedstock. Therefore, it needs to be utilized not just as a fuel but for both biochemical and thermochemical conversion through biorefining. LÄS MER
