1. Ädelmetallkatalysatorer för förbränning av kolväten i lösningsmedelsutsläpp
Sammanfattning : .... LÄS MER
2. In situ Studies of Platinum Catalyst Sintering
Sammanfattning : The damaging effect of pollutants from combustion engine exhaust on human health and environment is well recognized. Since the 70s, the three-way catalytic converter (TWC) has substantially improved the urban air quality by simultaneous conversion of CO, NOx and unburned hydrocarbons to O2, N2 and H2O. LÄS MER
3. Studies of catalyst sintering during operating conditions
Sammanfattning : The damaging effect of pollutants from exhaust gas of combustion engines on the human health and the environment is well recognized. Since the 70s, the three-way catalytic converter (TWC) has substantially improved the urban air quality by simultaneous conversion of CO, NOx and unburned hydrocarbons to O2 , N2 , CO2 and H2O.

4. Mixed metal oxide - noble metal catalysts for total oxidation of volatile organic compounds and carbon monoxide
Sammanfattning : CO, volatile organic compounds, and polyaromatics areubiquitous air pollutants that give rise to deleterious healthand environmental effects. Such compounds are emitted, forinstance, by the combustion of wood, particularly fromsmall-scale heating appliances. LÄS MER
5. Kinetic Studies of NOx Storage and Reduction Catalysts - Flow Reactor Experiments and Microkinetic Modeling
Sammanfattning : 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.
