| Description
| - Development of a multi-scale model of catalytic monolith for conversion of exhaust gases is discussed. Three types of models on different hierarchical levels are presented: 1. Spatially 3D model of meso-porous -Al2O3 particles with deposited crystallites of noble metal (catalytic sites), based on digital reconstruction utilizing TEM images of the catalyst. Typical size of the studied element is on the order of 100 nm ? 1 mm. The model describes effects of small pores (~ 10 nm) morphology, noble metals distribution, and size of the crystallites on the local reaction rate. 2. Spatially 3D model of a section of active catalytic layer (typical thickness 30 mm) ? monolith washcoat, consisting of Pt/-Al2O3 particles described in detail in model 1. The model utilizes digital reconstruction techniques of porous media on the basis of SEM images, and detailed solution of reaction-transport processes inside the washcoat layer. From this model, spatially averaged reaction rate and effectiveness factor ar

- V této práci je představen více-urovňový model konverze výfukových plynů. Model je uvažován na třech rozměrových urovních: 1. Prostorový 3D model meso-porésních částic g-Al2O3 s nanesenými krystalky vzácných kovů (katalytická centra) 2. Prostorový 3D model části aktivní katalytické vrstvy (typicky o tloušťce 30 mm) obsahující částice Pt/g-Al2O3 popsané v modelu 1. 3. Pseudo 1D a 2D model kanálku monolitu Dále je ukázáno spojení modelů na 2. a 3. urovni. Výsledky simulací na jednotlivých rozměrových urovních jsou zde diskutovány. (cs)
