6. Catalytic Reduction of NOx on Heavy-Duty Trucks
Sammanfattning : The objective of the work described in this thesis is to identify the principles and parts of an aftertreatment system for the catalytic NOx reduction for heavy-duty diesel vehicles, and to demonstrate such a system in full-scale. The reducing agent is diesel fuel. LÄS MER
7. Reduction of N₂O emissions from fluidized bed boilers through gas injection
Sammanfattning : .... LÄS MER
8. Redox Reactions of NO and O2 in Iron Enzymes : A Density Functional Theory Study
Sammanfattning : In the present thesis the density functional B3LYP has been used to study reactions of NO and O2 in redox active enzymes.Reduction of nitric oxide (NO) to nitrous oxide (N2O) is an important part in the bacterial energy conservation (denitrification). LÄS MER
9. Nitrous Oxide Formation over Zeolite-based Catalysts during Ammonia-SCR: The Effect of Framework Structure, Acidity, and Copper Content
Sammanfattning : The emission control of anthropogenic nitrous oxide (N2O), a by-product formed through fossil- and renewable fuel combustion, agricultural activities, and industrial chemical processes, has attracted large considerations due to its substantial contribution in global warming and ozone layer depletion. Selective catalytic reduction with ammonia (NH3-SCR) is the most prevailing technology for the abatement of nitrogen oxides (NOx) in the exhaust gases from lean-burn processes, with the possible formation of N2O.

10. Novel catalysts development for NOx reduction from H2 combustion engines
Sammanfattning : Hydrogen, as a clean energy carrier, burns without producing any carbon emissions. Hydrogen internal combustion engines (H2-ICE) are considered an alternative for the transition from conventional fossil-fuel vehicles. LÄS MER
