| Popis: | This present research aims at studying the kinetic reaction of HMF oxidation which is influenced by temperature gradient and Mn/Ni cation ratio in a lanthanum-based perovskite oxide catalyst. The result can be a fruitful database for the further development of the semi-industrial FDCA derivatives production process. Three Mn/Ni cation ratios of LaMnO3-d, LaMn0.5Ni0.5O3-d, and LaNiO3-d catalysts were selected and prepared by the Sol-Gel method. The bulk chemical species and oxidation states of secondary metal elements (Mn and Ni) for all synthesized perovskite-oxide catalysts were characterized by X-ray absorption near edge structure (XANES). The result of the distinct ratio of Mn3+/Mn4+ ions significantly affected the oxidation reaction of HMF. The LaMn0.5Ni0.5O3-d and LaMnO3-d catalysts achieved high catalytic performance for the HMF oxidation reaction at 120 °C for 4 hrs. The kinetic parameters and activation energy were successfully estimated and reported. |
