Реферат: Propane oxidation reaction over Pd/Al2O3 catalysts with different Pd nanoparticles sizes was studied in this work. The dependence of catalytic activity from several parameters such as the reaction temperature and C3H8:O2 ratio in inlet gaseous mixture was revealed. The increase of TOF values with particles size growth was found for propane combustion reaction. It is shown that reaction path can be changed from total oxidation to steam conversion of propane in CHx-rich mixtures and at higher temperatures. Moreover, the selectivity towards CO in steam conversion reaction is higher for the catalyst with the smallest mean diameter of palladium nanoparticles. XPS in-situ was used to show that palladium active state in propane oxidation reaction is mixed Pd0-PdO state. Furthermore, Pd0/PdO ratio in the active component straightly correlates with TOF values for the total propane oxidation reaction.
