The objective of this study was to depict the kinetic behavior of the platnum catalyst for the deep oxidation of BTX. The oxidation kinetics of BTX were studied on a 0.5% Pt /γ-Al₂O₃ catalyst at temperature ranging from 200 to 350℃ and the inlet concentration ranging from 133 to 333 ppmv. An approach based on the two-stage redox model was used to analysis the results. The conversions of BTX were increased as the inlet concentration was decreased and the reaction temperature was increased. The maximum deep conversion of benzene, toluene and m-xylene were 95.81%, 72.20% and 65.70% at 350℃, respectively. A simple multicomponent model based on two-stage redox rate model made reasonably good predictioons of conversiooon over the range of parameters studied. The kinetic parameters of multicomponent model were independently evaluated from the single compound oxidation experiments. Toluene and m-xylene conversion was inhibited by benzene. The reaction model reveals that tere is a competition between the two reactants for the oxidized catalyst. Benzene competes more effectively for the oxidized site and is thus oxidized more rapidly.
