摘    要:利用低压层流预混火焰结合同步辐射真空紫外光电离技术和分子束取样质谱技术,探测到并计算了甲醇摩尔掺混比为0%、11%、28%和50%的甲醇/正庚烷/氧气/氩气火焰中62种燃烧中间产物和最终产物的摩尔分数.结果发现,甲醇的加入对正庚烷的消耗速率和大分子裂解没有影响,其主要作用表现在对C1和C2小分子摩尔分数的影响.甲醇的氧...

关 键 词:甲醇  正庚烷  低压层流预混火焰  同步辐射

Abstract:An experimental study of the low pressure premixed laminar methanol/n-heptane/oxygen/ argon flame with the methanol mole fraction blend ratio of 0%,11%,28%,50%was performed with the tunable synchrotron vacuum ultra-violet(VUV) photoionization and molecular-beam sampling mass spectrometry.62 kinds of combustion intermediates and final products were detected as well as their mole fractions.The results show that the consumption rate of n-heptane and the dissociation of large molecular are not impacted by the m...
Keywords:methanol  n-heptane  low pressure premixed laminar flame  synchrotron radiation
