本文介绍了甲苯氧化的实验和模拟研究。在连续流搅拌釜式反应器中研究低温氧化，在以下实验条件下通过气相色谱分析含碳产物：温度为873至923 K，1巴，燃料当量比为0.45至0.91，甲苯浓度为1.4至1.7%，停留时间为2 - 13秒，对应于甲苯转化率为5 - 85%。在1305 ~ 1795 K温度和8.7 +/- 0.7 bar压力下，测量了当量比为0.5 ~ 3的甲苯-氧-氩混合气在反射激波后的点火延迟。详细的动力学机制已被提出来重现我们的实验结果，以及在其他激波管和活塞流反应器中获得的一些文献数据。通过灵敏度和通量分析确定了主要反应途径。(C)2004 Wiley Periodicals，Inc.
This paper describes an experimental and modeling study of the oxidation of toluene. The low-temperature oxidation was studied in a continuous flow stirred tank reactor with carbon-containing products analyzed by gas chromatography under the following experimental conditions: temperature from 873 to 923 K, 1 bar, fuel equivalence ratios from 0.45 to 0.91, concentrations of toluene from 1.4 to 1.7%, and residence times ranging from 2 to 13 s corresponding to toluene conversion from 5 to 85%. The ignition delays of toluene-oxygen-argon mixtures with fuel equivalence ratios from 0.5 to 3 were measured behind reflected shock waves for temperatures from 1305 to 1795 K and at a pressure of 8.7 +/- 0.7 bar. A detailed kinetic mechanism has been proposed to reproduce our experimental results, as well as some literature data obtained in other shock tubes and in a plug flow reactor. The main reaction paths have been determined by sensitivity and flux analyses. (C) 2004 Wiley Periodicals, Inc.
