1. Experimental and Modeling Studies of Sulfur-Based Reactions in Oxy-Fuel Combustion
Abstract : Oxy-fuel combustion is a technology for CO2 capture that is suitable for large-scale, coal-fired power plants. In this system, the combustion air is replaced by a mixture of O2 and recycled flue gases, so as to enrich for CO2 in the flue gas. READ MORE

2. The Fate of Sulfur during Oxy-Fuel Combustion
Abstract : Oxy-fuel combustion, where air is replaced by O2 and recycled flue-gas to enrich combustion products, is one of the main CO2 capture technologies suitable for large-scale coal-fired power plants. The changed combustion conditions in oxy-fuel combustion influences the sulfur chemistry, which has recently been the subject of increased attention due to the importance of sulfur species in corrosion and flue-gas cleaning issues.

3. Fundamentals of NH3-SCR and SOx chemistry over copper zeolite for the control of NOx and greenhouse gas (N2O) emissions
Abstract : The release of N2O over Cu-zeolite was investigated due to the critical contribution it makes to the atmosphere as one of the greenhouse gases (GHGs). An exhaust after-treatment system (EATS) for heavy-duty vehicles that uses Cu/SSZ-13 as the selective catalyst reduction (SCR) catalyst experiences not only a variety of flow, temperature and chemical conditions but is also exposed to various resulting contaminants.

4. Surface Reactivity and Electronic Structure of Metal Oxides
Abstract : The foci of this thesis are the metal oxides Cu2O, ZnO and Fe3O4 and their interaction with water and sulfur dioxide (SO2). The intention is to study SO2-induced atmospheric corrosion on a molecular level. All studies are based on photoelectron spectroscopy (PES) and scanning tunneling microscopy (STM) measurements.

5. Groundwater defluoridation by natural minerals : Understanding the process of fluoride removal from drinking water sources in Tanzania
Abstract : Fluoride (F-) concentration in drinking water is one of the water quality parameters in countries with high concentrations in groundwater sources. Natural minerals have shown considerable effectiveness in F- removal. READ MORE
