During the COVID-19 lockdown (24 January–20 March) in China low air pollution levels were reported in the media as a consequence of reduced economic and social activities. Quantification of the pollution reduction is not straightforward due to effects of transport, meteorology, and chemistry. We have analyzed the NO<sub>x</sub> emission...

Leune, Benjamin (author)
Anthropogenic nitrogen dioxide (NO₂) in the troposphere is mainly produced by combustion engines in traffic, industry and energy production, and continues to affect air quality, human health and environment. Daily global measurements of tropospheric NO₂ columns are obtained by satellites with increasing spatial resolution and signal-to-noise...

Sutopo, Kinanthi (author)
Aviation is a large contributor to anthropogenic climate change through its emissions, particularly through nitrogen oxides (NOx), which reacts to Ozone in the atmosphere. Due to the emission of NOx, the ozone budget of the atmosphere is disturbed which results in an increase in the Earth’s surface temperature. To mitigate this effect, the...

The Flameless Combustion (FC) regime has been pointed out as a promising combustion technique to lower the emissions of nitrogen oxides (NOx) while maintaining low CO and soot emissions, as well as high efficiencies. However, its accurate modeling remains a challenge. The prediction of pollutant species, especially NOx, is affected by the...

The formation of NOx in diesel engines is heavily influenced by the amount of available oxygen and the combustion temperature. This thesis investigates the effects of the implementation of exhaust gas recirculation on the NOx emissions of a 4-stroke marine diesel engine. With EGR implemented a part of the fresh intake air is replaced by exhaust...

de Bruin, Joep (author)
Horizontal drilling and hydraulic fracturing have increased unconventional oil and gas extraction from shale reserves in the U.S. in the last decade, making up more than half of total U.S. oil and gas production at present. This activity results in NOx emissions in the extraction regions that are measurable from space using the Ozone Monitoring...

Cattaneo, Federico (author)
Environmental regulations are continuously raising the bar towards more advanced diesel engine designs ca- pable of minimizing the emissions of polluting substances. The recent IMO Tier III legislation, entered into force in 2016, is forcing the engine manufacturers to meet a NOx reduction of more than 70% from Tier II for all the ships sailing...

Nitrogenoxides (NOx, including NO and NOx) are a group of hazardous, toxic and harmfulgasses, which have an adverse effect on both environment and human health,e.g., acid rain, photochemical smog, and affecting the human respiratorysystem. The NOx concentration in most of the EUcities exceeds the EU annual limit value (40 μg/m3). Around40% of...

Mild combustion in a lab-scale furnace has been experimentally and numerically studied. The furnace was operated with Dutch natural gas (DNG) at 10 kW and at an equivalence ratio of 0.8. OH∗chemiluminescence images were taken to characterize the reaction zone. The chemiluminescence intensity is relatively low compared to conventional flames...

Wu, Q. (author)
Conventional TiO2 based photocatalysts oxidize NOx to nitrates which do not automatically desorb and have to be washed away from the catalyst surface. To avoid this, the research described in this thesis aims to design new photocatalysts that can photo-reduce NO into N2 and O2. Previous efforts in the literature have shown that catalysts...

Contemporary architecture is increasingly influenced by the concept of landscape, and this is particularly the case in the Netherlands. Like at many other places, a new mindset is emerging, transforming the core values of the disciplines of architecture and urbanism with the notion of the organization of architectural space as a landscape....

Decision support model that determines which air emission reduction technologies can be installed on a ship, such that the ship will comply with IMO ANNEX VI Regulation 13 (NOx regulation). Consecutively, the model will determine which remaining air emission reduction technology is the cheapest so a long term cost-efficient decision can be taken.

Di Nola, G. (author)
This dissertation investigates the impact of various biomass fuels and combustion conditions on the NOx emissions during biomass co-firing. Fossil fuels dominated the energy scenario since the industrial revolution. However, in the last decades, increasing concerns about their availability and environmental risks related with their extensive...

Adouane, B. (author)
Biomass-derived LCV (Low Calorific Value) gas represents one of the best alternatives for fossil fuels. It is very attractive, because it is CO2 neutral as biomass consumes an amount of CO2 when growing and releases almost the same amount when combusted. However, the raw gasifier producer gas contains a high content of fuel-bound nitrogen (FBN),...

Kumaraswamy, R. (author)
Nitric oxide (NO) and nitrogen dioxide (NO2) are both important Green house gases, which also cause air pollution. Industrial flue gas emissions are responsible for 17% of NOx/SOx released into the atmosphere. Treatment of flue gas to remove NO and NO2 had started a few decades ago and several chemical and biological processes have been...
