چکیده
|
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 (r^2 > 0.99) is more suitable for predicting the conversion of toluene than the power law model (r^2 = 0.53), and the mars-van krevelen model can accurately express the reaction rate of this process.
