1. 16. Residues from biochemical production of transport biofuels in Northern Europe : combustion properties and applications

   Författare :Gunnar Eriksson; Bengt Johan Skrifvars; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

   Sammanfattning : Residues from biochemical production of liquid transport biofuels will probably become available for energy use if more gasoline and diesel is substituted. For processes used in northern Europe they amount to 35-65 % of the feedstock energy and despite interest from energy companies, their fuel properties are largely unknown. LÄS MER

3. 17. Utilization of local bioresources for transport fuels - System analysis for decision support

   Författare :Muhammad Arfan; Ola Eriksson; Jonas Ammenberg; Högskolan i Gävle; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System analysis; local bioresources; transportation fuels; LCA; LCC; geography of transitions; Systemanalys; Lokala resurser; drivmedel; LCA; LCC; geografi och om-ställning;

   Sammanfattning : This thesis presents a comprehensive system analysis of the utilization of biowaste and forest industry residues to produce transportation fuels. It explores various aspects such as the constraints to the production system’s value chain development, the utilization of the geographical proximity of biofuel technology innovation system components, environmental impacts, and economic costs.

4. 18. Alphavirus-host interactions : how to unravel the proviral activity of G3BP

   Författare :Benjamin Götte; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : The genus Alphavirus belongs to the virus family Togaviridiae, a group of arthropod-borne enveloped RNA viruses with single-stranded, positive-sense genome. Members of this genus can be found worldwide and are geographically distinguished into Old World and New World alphaviruses. LÄS MER

5. 19. Mild Wet Torrefaction and Characterization of Woody Biomass from Mozambique for Thermal Applications

   Författare :Carlos Alberto Cuvilas; Weihong Weihong Yang; Tobias Richards; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomass; Wet torrefaction; Fast Pyrolysis; kinetics; Catalyst;

   Sammanfattning : Mozambique has vast forestry resources and also considerable biomass waste material such as bagasse, rice husks, sawdust, coconut husks and shells, cashew nut shell and lump charcoal waste. The potential of the total residues from the agricultural sector and the forest industry is estimated to be approximately 13 PJ. LÄS MER

7. 20. Slag formation in fixed bed combustion of phosphorus-poor biomass

   Författare :Ida-Linn Näzelius; Marcus Öhman; Bengt-Johan Skrifvars; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomass; slagging; fixed bed; Energiteknik; Energy Engineering;

   Sammanfattning : To handle a great demand for biomass, alternative biomasses beyond stem wood are being introduced into the solid fuel combustion market, fuels with generally higher (>0,5 wt-%) ash content and different fuel ash compositions compared to stem wood, such as forest residue, bark, grass and straw. Unfortunately, combustion of these alternative fuels often causes more ash related problems such as fouling, slagging and higher particle emissions compared to combustion of stem wood. LÄS MER
