1. 6. Microbial Fuel cells, applications and biofilm characterization

   Författare :Adolf Krige; Paul Christakopoulos; Sebastià Puig; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MFC; Microbial fuel cell; Raman microscopy; BES; Geobacter sulfurreducens; Biokemisk processteknik; Biochemical Process Engineering;

   Sammanfattning : Since the 1900’s it has been known that microorganisms are capable of generating electrical power through extracellular electron transfer by converting the energy found organic compounds (Potter, 1911). Microbial fuel cells (MFCs) has garnered more attention recently, and have shown promise in several applications, including wastewater treatment (Yakar et al. LÄS MER

3. 7. Microbial communities in biological electrochemical systems

   Författare :Marie Abadikhah; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; viruses; microbial ecology. microbial electrolysis cells; bioelectrochemical system; biocathode; bioanode; microbial community assembly;

   Sammanfattning : Biological electrochemical systems (BES) can be used as biosensors and for recovery of resources from waste streams. BES utilizes microbial communities that grow on the surface of electrodes in the form of biofilms. LÄS MER

4. 8. Fermentative hydrogen and methane productions using membrane bioreactors

   Författare :Julius Akinbomi; Högskolan i Borås; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Encapsulation; Inhibition; hydrodynamics; hydrogen; methane; fruit flavour; Membrane bioreactor; Resursåtervinning; Resource Recovery;

   Sammanfattning : The role of energy as a stimulant for economic growth and environmental sustainabilityof any nation has made the focus on green fuels, including fermentative hydrogen (bioH2) andmethane (bioCH4), to be a priority for the World’s policy makers. Nigeria, as the most populousAfrican country, with worsening energy crisis, can benefit from the introduction of the bioH2 andbioCH4 technologies into the country’s energy mix, since such technologies have the potential ofgenerating energy from organic wastes such as fruit waste.

5. 9. Excess heat utilisation in oil refineries - CCS and algae-based biofuels

   Författare :Viktor Andersson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; techno-economic; CO2 emissions; carbon dioxide; renewable diesel; post-combustion; algae biofuels; process integration; GHG emissions; oil refining industry; carbon capture and storage CCS ;

   Sammanfattning : The main objective of this thesis is to investigate two different concepts for CO2 mitigation, from a system perspective, in relation to the oil refining industry: CO2 capture and storage; and algae-based biofuels. For all these processes, process integration with an oil refinery is assumed. LÄS MER

7. 10. Enhancement of Volatile Fatty Acid Production from Dairy Wastewater

   Författare :Merve Atasoy; Zeynep Cetecioglu; Juan Lema; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Volatile fatty acid; mixed culture fermentation; pure culture; bioaugmentation; bacterial community; Flyktiga fettsyror; jäsning med blandkultur; renkultur; bioaugmentering; bakteriesamhälle; Chemical Engineering; Kemiteknik;

   Sammanfattning : Resource recovery from waste-streams is a highly promising approach to meet with urbanization and modernization consequences. Rapid human population growth, expanding industrialization and excessive consumption of resources lead to increasing demand for raw materials and energy sources, and an escalation of greenhouse gas emission.
