1. Palladium Catalyzed Methane Oxidation for Emission Control
Sammanfattning : The use of methane based fuels, such as natural gas and biogas, benefits from lower emissions of CO2, CO, NOx, non-methane HC, SOx and particulate matters compared to traditionally used liquid fossil fuels. However, the exhaust gases contain significant levels of unburnt CH4 residuals, which are desirable to minimize since CH4 is a strong greenhouse gas with high global warming potential. LÄS MER
2. 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
3. Mechanism of the passive NOx adsorption process on zeolite-supported Pd in controlling cold-start emissions
Sammanfattning : Passive NOx adsorbers (PNA) have been used for preventing NOx emissions being released during a cold start. This method involves trapping NOx on an adsorbent at low temperatures and releasing them later, when the exhaust temperature exceeds 200℃. LÄS MER
