摘要：

A kinetic study of n-butanol catalytic combustion over the Pt/ZSM-5 was performed in a fixed-bed combustor at ambient pressure and temperature range in 390-470 K. The Power Law model and Langmuir-Hinshelwood (L-H) model were constructed to characterize the n-butanol catalytic oxidation. The reaction orders of n-butanol and O-2 were -0.24 and 1, respectively. Five pathways rate expressions were selected to predict the reaction rate for L-H model. The sum of the squared differences between the experimental data and the fitted data indicated that surface reaction and oxygen adsorption were probably rate-determining steps. The reliability of the rate expressions was affirmed by comparing the experimental and the fitted rates.
