It has been established that the reaction of ketene formation take place on the surface of nanosized oxides SiO2, Al2O3, Al2O3/SiO2 and TiO2/SiO2 and don't take place on the surface of the nanocomposites CeO2/SiO2. The kinetic parameters of ketenization and ketonization reactions have been calculated. And on this basis probable mechanisms of heterogeneous catalytic thermal transformations have been suggested. It has been found that the temperature of the maximum reaction rate and activation energy of ketenization reaction on the surface of nanosized oxides decreases in the series: SiO2> Al2O3> SiO2/TiO2> SiO2/Al2O3. It has been established that the symmetrical ketones are formed on the surface of synthesized nanocomposites CeO2/SiO2 and Al2O3. It has been shown that the development of nanocatalysts based on cerium oxide is promising as the temperature Tmax of the maximum rate of the catalytic reaction of symmetrical ketones (dibutylketone) on surface of nanocomposite CeO2/SiO2 is by 70 C lower than temperature Tmax on Al2O3 surface. There is 16 kJ/mol less activation energy respectively. Therefore the energy efficacy of use of such catalysts will be higher. Product Description popup.authors Б.Б.Паляниця К.С.Кулик Кулик Т.В.
