摘要

本研究建立了旋转填料床（PRB）中高重力强化Fe-MnOX/ ac催化臭氧化苯酚的表观反应动力学模型。结果表明，该模型能较准确地预测苯酚的去除率，实验值与理论值的偏差小于8%。得到了臭氧直接反应和·OH间接反应的速率常数及RCT参数，从而更准确地估计了它们对苯酚脱除的贡献。直接反应（fO3）的贡献率为77.5%，间接反应（f•OH）的贡献率为22.5%。本研究为建立非均相催化臭氧化有机物的动力学模型提供了可行的方法，并对臭氧与苯酚的直接和间接反应机理有了新的认识。

A kinetic model for high-gravity intensified Fe-MnOX/AC-catalyzed ozonation of phenol: Direct and indirect reaction

In this study, an apparent reaction kinetic model is established for high-gravity intensified Fe-MnO_X/AC-catalyzed ozonation of phenol in a rotating packed bed (PRB). It is found that this model can accurately predict the removal rate of phenol, with the deviations between experimental and theoretical values being less than 8%. The rate constants of the direct reaction of ozone and the indirect reaction of ·OH and the parameter R_CT are obtained, based on which their contributions to the removal of phenol can be more accurately estimated. The contribution factor is 77.5% for the direct reaction (f_O3) and 22.5% for the indirect reaction (f_•OH), respectively. This study provides a feasible method to establish the kinetic model for heterogeneous catalytic ozonation of organic matter, as well as new insights into the direct and indirect reaction mechanism of ozone with phenol.
