Abstract:
A low-pressure premixed gasoline/oxygen/argon flame was studied by using molecular-beam sampling mass spectrometry combined with a tunable synchrotron radiation photoionization technique. The photoionization time-of-flight mass spectrum of gasoline/oxygen/argon in the flame was recorded and the ionization energies of some species were detected. Compared with the ionization energies in literatures, the isomers were uniquely identified. The reaction process of five typical hazardous products was empirically analyzed by species concentration profiles. The experimental results are helpful in establishing the kinetic modeling for a gasoline/oxygen flame.

摘要:
利用同步辐射和分子束取样技术研究了汽油与氧气低压预混火焰的燃烧产物,得到汽油燃烧火焰中部的光电离飞行时间质谱图以及一些成分的电离能.与文献中的电离能比较后可以确定火焰中产物的具体结构.通过空间分布曲线着重分析了五种有害物质的反应过程,为建立燃烧反应动力学模型奠定了基础.
