This paper reports on-line analyses of the soot emissions from the Inner Mongolia bituminous coal combustion and pyrolysis processes with a vacuum ultraviolet photoionization aerosol time-of-flight mass spectrometer (VUV-ATOFMS). The soot particles are generated by heating a small amount of screened coal powder in synthetic air and nitrogen atmosphere in a tubular oven. The vacuum ultraviolet photoionization time-of-flight (VUV-TOF) mass spectra of the soot particles emitted from combustion and pyrolysis at different oven temperatures and different stages are obtained. The VUV-TOF mass spectra are assigned with the references of the results of the off-line GC/MS analysis.
本文报道了利用真空紫外光电离气溶胶飞行时间质谱仪（VUV-ATOFMS）对内蒙古烟煤燃烧和热解过程中烟尘排放进行的在线分析。烟尘颗粒是通过在管式炉中在合成空气和氮气气氛中加热少量筛分后的煤粉产生的。获得了在不同炉温及不同阶段燃烧和热解产生的烟尘颗粒的真空紫外光电离飞行时间（VUV-TOF）质谱。VUV-TOF质谱参考离线GC/MS分析结果进行了归属。
