催化燃烧有助于燃烧污染物的排放控制和超音速发动机内燃烧的点火和维持。构建一个包含催化点火和催化氧化机理的可用于大尺度模拟的反应动力学模型是相关工程领域的客观需求，而对小分子模型燃料在各种工况条件下的验证实验是构建该模型的基础。针对现有的催化点火基础研究不够系统、数据缺乏的问题，本项目拟利用微量热法和在线质谱分析等技术对包含甲烷、乙烷、丙烷、正丁烷和乙烯、丙烯等的小分子模型燃料在钯/氧化钯（Pd/PdO）作用下的催化点火机理进行系统研究。获得点火温度、催化放热、表面反应活化能等宏观实验数据，以及催化剂周围气相氛围的物种浓度等微观实验数据。探究压力、浓度、当量比等外界因素对催化点火的影响。在此基础上，将催化表面反应与详细的气相反应机理相结合，构建初步的小分子烃类在Pd/PdO作用下的催化点火模型，并进行实验验证。这个模型将为以后实用的、具有预测功能的催化燃烧模型的建立提供基础。

Catalytic combustion helps to reduce the air pollution emission and also help to ignite and enhance the flame stability in scramjet engines.A catalytic combusiton model including ignition and oxidation mechanism which can be used in large scale simulation is highly desired by the related engineering fields.Such a model need to be validated by a lot of experimental data under various conditions. Because a systemic research on catalytic ignition is still scarce in literature, this project will use microcalorimetry as well as mass spectrometry to perform the mechanism study of the catalytic ignition of small model fuels over palladium/palladium oxide.The globle parameters including ignition temperature, heat release rate and the activation energy, as well as the mole fractions of the major gas phase species around the palladium wire will be measured. The effects of the pressure, concentration and stoichiometry on catalytic ignition will be revealed. A ignition model for these fuels over palladium will be built by combining the catalytic reactions with the detailed gas-phase reaction mechanism, which will be tested by the aforementioned ignition characteristics. This model will contribute to the the building of a practical, predictive catalytic combustion model for future engine design.
