2. 6. Sustainable Energy Conversion from Biomass Waste Combustion - Experimental and Multiscale Modelling Studies

   Author : Maulana Nugraha; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stefan flow; particulate matter; biomass; combustion; soot; furnace; orthogonal collocation; CFD simulation;

   Abstract : The development of sustainable energy conversion via residual biomass combustion is one of the scientific and industrial community focus today to fulfilling the global net zero emission commitment in 2050. Despite its potency due to the abundant stock of biomass, hazardous particulate matter (PM) emission from residual biomass combustion remains a big challenge to increase the contribution of biomass combustion as a main renewable energy source.

4. 7. Anaerobic treatment of wastewater in a UASB reactor

   Author : Larisa Korsak; Luis Moreno; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anaerobic treatment; UASB; granular biomass; methanogenic activity; modelling; axial dispersion; Chemical engineering; Kemiteknik;

   Abstract : The anaerobic treatment of waste water has been studied with an emphasis on the Up- flow Anaerobic Sludge Blanket (UASB) reactor. A model to describe the processes occurring in a UASB reactor was developed and an experimental study of the anaerobic wastewater treatment systems in Nicaragua was also performed. READ MORE

5. 8. Chemical Interactions between Potassium, Nitrogen, Sulfur and Carbon Monoxide in Suspension-Fired Systems

   Author : Thomas Allgurén; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sulfation; combustion; CO-oxidation; modelling; oxy-fuel; NO-formation; experiments; alkali;

   Abstract : Drastic cuts in global CO2 emissions are needed to mitigate global warming and limit the average temperature increase to well below 2ºC. The power generation sector is largely based on fossil fuels and generates a significant share of the global CO2 emissions. READ MORE

6. 9. The anode and the electrolyte in the MCFC

   Author : Andreas Bodén; Göran Lindbergh; Carina Lagergren; Takao Watanabe; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; composite electrolytes; electrode kinetics; nickel solubility; porous electrode; reformate; water-gas shift reaction; electrolyte; electrolyte distribution; hydrogen oxidation reaction; ion segregation; mass transport; mathematical modelling; MCFC; molten carbonate fuel cell; Chemical engineering; Kemiteknik;

   Abstract : A goal of the Swedish government is to increase the usage of renewable fuels and biomass-based fuels. Fuel cells, and especially the MCFC, are useful for these types of fuels. The Swedish market may benefit from the MCFC in two ways: increased efficiency of the biofuels and also utilisation of produced heat in district heating. READ MORE
