Abstract
Reaction behaviors and kinetics of catalytic oxidation of toluene with different feed flows over Pt/Zr(x)-HMS catalysts with Si/Zr ratio
equal to 5, 10, 20 and 35 were investigated over a wide temperature range (200-500 °C). Results show that Pt/Zr(x)-HMS has the best
catalytic performance. The kinetics data were fitted by the Power-law and Mars-van Krevelen kinetics models. The fitting results show that
the Mars-van Krevelen model (R2 > 0.99) is more suitable for predicting the conversion of toluene than the Power law model (R2 = 0.53),
and the Mars-van Krevelen model can accurately express the reaction rate of this process.
