1. 11. Fungi-Based Biorefinery : Valorization of industrial residuals and techno-economic evaluation

   Författare :Gülru Bulkan; Mohammad J Taherzadeh; Mats Galbe; Högskolan i Borås; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Techno-economic analysis; Organosolv; bioethanol; filamentous fungi; food; lignin; fruit; bioactive compounds; Resource Recovery; Resursåtervinning;

   Sammanfattning : Sustainable development of society and industry is necessary for a safer future that is being challenged by environmental pollution, climate change, and scarcity of food and nutrition. Materials considered as waste can be converted into value-added products and energy, hence regained to the economy. LÄS MER

3. 12. Efficiency Improvements in Waste-to-Energy Combustion Processes : Method Development and Evaluation

   Författare :Eboh Francis Chinweuba; Simon Harvey; Högskolan i Borås; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solid waste; exergy; entropy; higher heating value; improvement potential; waste-to-energy plant; efficiency improvement; cost evaluation; simulation; modelling; Resource Recovery; Resursåtervinning;

   Sammanfattning : is the energy recovery method. The electrical efficiency of this technology, however, is generally low when compared with other solid fuel-fired combustion plants as a result of low steam properties. Furthermore, there is lack of efficient methods to evaluate the performance of this system. LÄS MER

4. 13. Lignocellulosic Ethanol Production Based on Steam Pretreatment and SSF: Process Development through Experiments and Simulations

   Författare :Per Sassner; Avdelningen för kemiteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process simulation; Energy efficiency; SSF; Enzymatic hydrolysis; Lignocellulose; Steam pretreatment; Ethanol production; Process economics; Flow-sheeting;

   Sammanfattning : Lignocellulosic materials, such as wood, waste products from the forestry industry, agricultural residues and herbaceous crops, serve as an abundant and comparatively cheap feedstock with the potential to be used for large-scale ethanol production. However, the complex structure of lignocellulosic materials, the presence of various hexose and pentose sugars in hemicellulose, and the presence of various compounds that inhibit the fermenting organism constitute physical barriers that add to the production cost and make full-scale introduction economically more risky.

5. 14. Systems Analysis of Chemicals Production via Integrated Entrained Flow Biomass Gasification : Quantification and improvement of techno-economic performance

   Författare :Jim Andersson; Eric D. Larson; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

   Sammanfattning : Lignocellulosic biomass gasification is a promising production pathway for green chemicals, which can support the development towards a more sustainable society where fossil fuels are replaced. To be able to compete with fossil fuels, a highly efficient production of biomassbased products is required in order to maximize overall process economics and to minimizenegative environmental impact.

7. 15. Ammonia-Based Post-Combustion Capture of Carbon Dioxide

   Författare :Henrik Jilvero; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CCS; Ammonia; Post-combustion;

   Sammanfattning : Post-combustion capture of carbon dioxide is one of the measures to reduce emissions of carbon dioxide from large point source emitters. In post-combustion capture the carbon dioxide is absorbed from the flue gas by means of a liquid absorbent. LÄS MER
