摘要：

Ethyl acetate production usually comes with a large amount of high concentration organic wastewater. This study proposed a method for treating ethyl acetate wastewater by vaporization followed with catalytic oxidation in a fixed-bed reactor using a self-made composite oxide catalyst. The reaction process was optimized and the apparent reaction kinetic data were obtained at 290~410 ℃ and φ = 4% oxygen concentration after eliminating the effects of catalyst external diffusion. The apparent reaction kinetic model based on oxygen consumption rate was established and its parameters were obtained via data fitting. The calculated apparent activation energy was 50.17 kJ∙mol-1. The calculated results were in agreement with the experimental data, and the model was verified with good accuracy. This study provides guidelines for the design of industrial catalytic oxidation reactors. © 2020, Editorial Board of "Journal of Chemical Engineering of Chinese Universities". All right reserved.
