   Nyckelord :Cashew nut shells; coconut shells; biomass; thermogravimetry; pyrolysis; kinetics; combustion; TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning :  Cashew nut and coconut shells are two potential renewable and environmentally friendly energy sources that are commonly found as agro-industrial wastes in tropical countries. Despite this fact, they are not yet widely studied as such. LÄS MER

3. 22. Thermochemical behavior of pretreated biomass

   Författare :Amit Kumar Biswas; Weihong Yang; Wlodzimierz Blasiak; Henrik Kusar; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomass; Pretreatment; therochemical conversion; pyrolysis; combustion; SRA - Energy; SRA - Energi; Energy Engineering;

   Sammanfattning : Mankind has to provide a sustainable alternative to its energy related problems. Bioenergy is considered as one of the potential renewable energy resources and as a result bioenergy market is also expected to grow dramatically in future. However, logistic issues are of serious concern while considering biomass as an alternative to fossil fuel. LÄS MER

4. 23. Conversion of biomass and waste using highly preheated agents for materials and energy recovery

   Författare :Pawel Donaj; Wlodzimierz Blasiak; Tobias Richards; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biomass; waste; pyrolysis; gasification; ASR; Metallurgical process engineering; Metallurgisk processteknik; SRA - Energy; SRA - Energi;

   Sammanfattning : One of the greatest challenges of human today is to provide the continuous and sustainable energy supply to the worldwide society. This shall be done while minimizing all the negative consequences of the operation(s) to the environment and its living habitants including human beings, taking from the whole life cycle perspective.

5. 24. Added value from biomass by broader utilization of fuels and CHP plants

   Författare :Christer Gustavsson; Roger Renström; Lars Nilsson; Pål Börjesson; Karlstads universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biofuels; bioeconomy; pyrolysis; gasification; leaching; Miljö- och energisystem; Environmental and Energy Systems;

   Sammanfattning : The present work, where additional value-creating processes in existing combined heat and power (CHP) structures have been examined, is motivated by a political- and consumer-driven strive towards a bioeconomy and a stagnation for the existing business models in large parts of the CHP sector.The research is based on cases where the integration of flash pyrolysis for co-production of bio-oil, co-gasification for production of fuel gas and synthetic biofuels as well as leaching of extractable fuel components in existing CHP plants have been simulated.

7. 25. Numerical Modeling of Turbulent Combustion and Flame Spread

   Författare :Zhenghua Yan; Institutioner vid LTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Technological sciences; Flame Spread; Pyrolysis; Heat Transfer; Radiation; CFD; Turbulent Combustion Modeling; Teknik;

   Sammanfattning : Theoretical models have been developed to address several important aspects of numerical modeling of turbulent combustion and flame spread. The developed models include a pyrolysis model for charring and non-charring solid materials, a fast narrow band radiation property evaluation model (FASTNB) and a turbulence model for buoyant flow and flame.
