It has been shown that the hydrogenation of ethylene on catalysts containing nanoparticles of iron on carbon nanotubes begins at a temperature of -30 0С. Formation of methane is fixed at temperatures above 250 0С, on pure BNT the formation of methane is not fixed. Determined that activity dependent on the size of the nanoparticles is nonlinear iron nanoparticles measuring 4.3 and 6.5 nm show practically the same activity, while in the range of 6.5 - 8.0 nm, an increase in activity. Thus, in a narrow range of sizes of iron nanoparticles of 1.5 nm (6.5 - 8.0 nm), an increase in activity is observed 7 times. In order to establish the size of the palladium nanoparticles with the greatest catalytic activity was investigated the influence of the size of nanoparticles of palladium in catalytic activity of Pd / ?-A12O3 in the process of hydrogenation of ethylene. Increasing the palladium nanoparticles in the size range of 2-6 nm in such composites leads to an increase in their activity, while the effective activation energy of the process remains virtually unchanged. According to the results of the study, it was concluded that the optimum size of the applied palladium nanoparticles in hydrogenation catalysts is in the range of 1-2 nm.5481 Product Description popup.authors Бичко Ігор Богданович Кайданович Зінаїда Володимирівна Калішин Євген Юрійович Трипольський Андрій Іккієвич popup.nrat_date 2020-04-02 Close
