中文摘要：
本文利用同步辐射真空紫外光电离质谱（SVUV-PIMS）技术研究了当量比为2．2的掺杂不同比例CO2的富燃乙烯低压层流预混火焰。发展了一个包含176个物种和642步反应的乙烯掺杂CO2的燃烧动力学模型。结果表明，反应CO＋OH=CO2＋H在掺杂CO2的火焰中对多环芳烃（PAH）的减少起着决定性的作用；随着掺杂CO2量的增加，1CH2、3CH2和CH等自由基的生成得到抑制，C2H2、C3H3和C4H4等碳黑前驱体生成也有所减少，因此推断后续产生的多环芳烃及碳黑等也将随着掺杂CO2量的增加而减少。
英文摘要：
Four rich premixed C2H4/O2 flames diluted with Ar and CO2 （total 30% in volume） at low pressure （4.0 kPa）, with respective CO2 proportions of 0%, 10%, 20% and 29%, were studied using synchrotron vacuum ultraviolet photoionization mass spectrometry. A kinetic model with 176 species and 642 reactions was developed. Based on the rate of production analysis and the sensitivity analysis, the reaction CO ＋ OH = CO2＋ H plays a significant role in the reduction of polycyclic aromatic hydrocarbons （PAHs） formation in the flames with CO2 addition. By increasing CO2 proportion, the formation of 1CH2, 3CH2, and CH is inhibited and the concentrations of C2H2, C3H3 and C4H4, which are soot precursors, are reduced as well as PAHs.
