LOW-PRESSURE PREMIXED LAMINAR DIMETHYL ETHER/OXYGEN/ ARGON FLAME WITH SYNCHROTRON RADIATION

利用同步辐射真空紫外单光子电离结合分子束质谱技术,对当量比(o)=1.5的低压预混层流二甲醚火焰进行了实验研究.通过测量光电离质谱和光电离效率曲线,探测到了二甲醚/氧气/氩气的燃烧产物和火焰中间物,包括不稳定的分子和自由基.通过测量离子信号的空间分布曲线,计算了二甲醚/氧气/氩气火焰的主要物种C2H6O、O2、Ar、H2、H2O、CO和CO2的摩尔分数曲线,以及主要中间物种如CH2O、C2H2、C2H4、CH3OH、C2H2O、C2H4O、CH3、CH4、HCO、C3H3和C3H4的摩尔分数曲线,并分析了主要中间物种的产生和消耗过程.
