1. Kinetic Studies of NOx Storage and Reduction Catalysts - Flow Reactor Experiments and Microkinetic Modeling
Abstract : The NOx storage and reduction (NSR) technology is a promising technique to reduce NOx during oxygen excess e.g. in lean burn engine exhaust. A typical NSR catalyst consists of the following components: precious metals, such as platinum, palladium or rhodium, a storage component, usually barium, and a high surface area support, such as γ-alumina.

2. Fundamental Studies of Catalytic NOx Removal - Micro Kinetic Modelling, Monte Carlo Simulations and Flow Reactor Experiments
Abstract : It is essential to decrease the CO2 emissions from vehicles, since CO2 is a greenhouse gas. One way to improve fuel economy and decrease CO2 emissions, is to run the engine with oxygen excess, so-called lean-burn operation. However, a major problem here is the reduction of the NOx in a lean atmosphere. READ MORE

3. Speeding up the Atmosphere : Experimental oxidation studies of ambient and laboratory aerosols using a flow reactor
Abstract : Apart from gases, the air we breath consist of tiny, so called, aerosol particles. A cubic metre of air in a relatively clean environment can consist of several billion aerosol particles. The impact of these particles on human health and on climate is significant. READ MORE

4. Studies of Supported Catalysts for Environmental Applications: - Flow Reactor Measurements, Monte Carlo Simulations and High Throughput Screening
Abstract : The use of heterogeneous catalysts for environmental applications, primarily for reduction of harmful emissions from vehicles and stationary sources, has successively increased during the last three decades. Driven by emission regulations, research and development within this area attract large interest and resources, especially for automotive applications. READ MORE

5. Entrained flow studies on biomass fuel powder conversion and ash formation
Abstract : Reducing the global dependence on fossil fuels is of paramount importance in tackling the environmental challenges we face, not only tomorrow, but already today. Biomass offers a renewable supply of CO2-neutral raw material that can be converted into many different forms of fuels and valuable chemicals, making it a prime candidate for the technologies of tomorrow.
