摘要：燃烧为现代社会提供了约80%的能源，在工业、运输、国防等领域均具有不可替代的作用。当前，燃烧学逐步从宏观现象学转向注重亚微尺度的湍流模拟和原分子层次的燃烧化学动力学研究，深入了解燃料组分、分子结构和燃烧条件与燃烧效率及污染物排放等的关系。开展对于航空燃料和新兴生物质燃料的燃烧本质和机理研究，在国家安全和能源战略等方面都具有重要意义。本年度主要针对真空紫外光电离技术在燃烧研究中的应用、航空燃料重要组分和生物质燃料燃烧化学动力学等方面开展了研究工作。在真空紫外光电离技术在燃烧研究中的应用方面，课题组将同步辐射真空紫外光电离质谱技术应用于常压层流预混火焰、煤热解和生物质热解等方面的研究，并在国际权威燃烧学期刊刊登文章，介绍对基于同步辐射的燃烧诊断方法的突破性发展以及在燃烧研究中的开拓性应用。在航空燃料重要组分和生物质燃料燃烧化学动力学研究方面，针对航空燃料重要组分甲基环己烷的热解及燃烧开展了实验和动力学模型研究，针对仲丁醇的热解和燃烧、正丁醇掺混的甲烷同轴扩散火焰和丙酸甲酯的低压热解开展了实验和动力学模型研究，对这些热点生物质燃料的燃烧化学动力学问题开展了深入的探索。

Annual report of combustion chemical kinetics research 2013
Abstract：Combustion provides over 80% energy supply for modern society， and plays irreplaceable roles in core fields such as industry， transportation and national defense. At present， combustion studies are moving from macroscale phenomenology to microscale turbulent simulation and combustion chemical kinetics， focusing on understanding the relationships of fuel compositions， molecule structures and combustion conditions with combustion efficiencies and pollutant emissions. In particular， the studies of combustion chemical kinetics of jet fuels and biofuels are very significant for national security and energy sustainability. In this year， our research focuses on the applications of vacuum ultraviolet （VUV） photoionization method in combustion research， combustion chemical kinetics of important components in jet fuels， combustion chemical kinetics of biofuels， and so on. For the first topic， we applied the VUV photoionization method in various combustion research fields， such as atmospheric pressure premixed flame studies， coal pyrolysis， biomass pyrolysis， and so on. We also published an invited paper on Proceedings of the Combustion Institute which is the most prestigious combustion journal， introducing our pioneering development of the synchrotron-based combustion diagnostic tool and applications of it in various fields of combustion research. In studies of combustion chemical kinetics of important components of jet fuels， we also performed an experimental and kinetic modeling investigation on the pyrolysis and oxidation of methylcyclohexane. In studies of combustion chemical kinetics of hot biofuels， we investigated the pyrolysis and oxidation of sec-butanol， the coflow diffusion n-butanol/methane flames and the low-pressure pyrolysis of methyl propionate. In 2013， we published over 37 papers on famous SCI journals in related fields， such as Proceedings of the Combustion Institute， Combustion and Flame， Journal of the American Chemical Society， Physical Review Letters， Review of Scientific Instruments， Energy & Fuels， Journal of Chemical Physics， Journal of Physical Chemistry C， Journal of Physical Chemistry C and Optical Letters， and finished the planned research targets.
