Anotácia knihy

Car exhaust catalysts were introduced in the early §1980 s, to limit the release of pollutants such as §hydrocarbons, carbon monoxide and nitrogen oxides. §These catalysts contain noble metals such as §palladium (Pd), platinum (Pt) and rhodium (Rh) and §are able to simultaneously abate all three of the §above-mentioned pollutants, hence the name three-way §catalyst (TWC). The exposure to high temperatures §(800-1000 °C) during operation and the presence of §additives in gasoline and lubricants will, after a §certain time, lower the activity of the TWC. High §temperatures reduce the active area by causing the §noble metals to agglomerate and sinter, whereas the §additives alter the activity either by fouling the §pores of the support material or by interacting with §the metals.§§The main objective of this work was to develop a §method which allows for the removal of contaminants §(additives) from the washcoat and enables the §redispersion of the active sites (noble metals), in §an effort to recover lost catalyst activity. For §this purpose, regeneration experiments were carried §out on a wide spectrum of different commercial car §exhaust catalysts.
