To build a set of complete kinetic parameters of oxygenated fuels kinetic model on Pt catalyst, methanol was used as an example to carry out the catalytic oxidation kinetics experiment of oxygenated fuels on Pt/ZSM-5 catalyst. The Power law model and Langmuir–Hinshelwood (L–H) model were established to characterise the catalytic oxidation reaction of methanol. Then the oxidation kinetics of methanol, ethanol, dimethyl ether (DME) and n-butanol on Pt/ZSM-5 was studied under the same experimental conditions. It was found that the reaction orders of fuel molecules (methanol is −0.14) were much less than that of oxygen (1.23) in Power law model. The adsorption constants of fuel molecules were higher than that of oxygen in L–H model. The adsorption characteristics of alcohols on Pt were similar, but the reaction orders of alcohols were not consistent. The adsorption constants and adsorption heat of dimethyl ether were much larger than that of alcohols. The intrinsic reaction rates of four oxygenated fuels on Pt/ZSM-5 were compared at the same input power: r_methanol$>$r_DME$>$r_ethanol$>$r_n-butanol. In general, methanol is a suitable oxygenated fuel in the design and development of catalytic micro-combustor.

为建立一套完整的含氧燃料在Pt催化剂上的动力学模型，以甲醇为例，开展了含氧燃料在Pt/ZSM-5催化剂上的催化氧化动力学实验。建立幂律模型和Langmuir-Hinshelwood（L-H）模型来表征甲醇的催化氧化反应。然后在相同的实验条件下研究了甲醇、乙醇、二甲醚(DME)和正丁醇在Pt/ZSM-5上的氧化动力学。在幂律模型中发现燃料分子（甲醇为-0.14）的反应级数远小于氧气（1.23）。在 L-H 模型中，燃料分子的吸附常数高于氧气。醇类在 Pt 上的吸附特性相似，但醇类的反应顺序并不一致。二甲醚的吸附常数和吸附热远大于醇类。在相同输入功率下比较了四种含氧燃料在 Pt/ZSM-5 上的固有反应速率：r_甲醇$>$r_二甲醚$>$r_乙醇$>$正_丁醇。一般来说，甲醇是催化微型燃烧器设计和开发中合适的含氧燃料。
