21. Crop production without fossil fuel : production systems for tractor fuel and mineral nitrogen based on biomass
Sammanfattning : .... LÄS MER
22. Chemical Interactions between Potassium, Nitrogen, Sulfur and Carbon Monoxide in Suspension-Fired Systems
Sammanfattning : 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. LÄS MER
23. Transition metal ion-chelating ordered mesoporous carbons as noble metal-free fuel cell catalysts
Sammanfattning : Polymer electrolyte membrane fuel cells offer promising possibilities for clean and efficient chemical to electrical energy conversion, though their high price makes them financially unappealing. This is to a large part due to the high cost of the noble metal catalyst used in fuel cells, which makes development of new, cheap and active catalyst materials necessary. LÄS MER
24. Combustion of selected alternative liquid fuels at oxy-fuel conditions: experiments and modelling
Sammanfattning : Combustion of fuels is a major source of energy and at the same time a threat to the environment. Carbon dioxide (CO2) emissions are one of the obstacles on the route to cleaner energy. Combining Carbon Capture and Storage-technology (CCS) with use of biofuels lead to a negative net release of CO2 can be achieved. LÄS MER
25. HCCI Combustion by Retaining Residuals. Development and Analyses of a Method to Reduce Fuel Consumption for Passenger Car Gasoline Engines
Sammanfattning : The demand for more powerful engines on one hand, and greater fuel-efficiency on the other, requires a revolution in engine combustion technology. Homogeneous charge compression ignition (HCCI) can be a fuel-saving, low emissions approach that seems to be very suitable for large displacement passenger car engines. LÄS MER
