主要利用热解-气相色谱/质谱联用技术(Py-GC/MS)对不同成熟度的家用蜂窝煤燃烧排放烟炱(soot)颗粒的化学特征进行研究,并探讨了成熟度对燃煤排放soot颗粒热解产物的影响。结果显示:不同成熟度的燃煤排放soot颗粒热解产生类似的产物。这些化合物均以芳香化合物(58.1%~92.0%)为主,另外还含有酚类化合物(0.66%~32.3%)、脂肪烃(0.21%~9.57%)、呋喃类化合物(1.42%~2.57%)、含硫化合物(NA~4.12%)和含氮化合物(NA~3.91%)等,表明不同成熟度蜂窝煤燃烧排放的soot颗粒都是以高度芳香性的结构为核心,连接有含氧、氮等杂原子基团组成。研究结果还显示,原煤成熟度对soot颗粒的热解特征具有一定的影响。总体上, soot颗粒热解产物中芳香化合物的百分含量随着煤样成熟度的增加呈现递增趋势,而酚类化合物的百分含量则随着煤样成熟度的增加逐渐降低,另外含氮化合物主要存在于低成熟度煤样燃烧排放的soot颗粒样品中。本文研究结果表明了随着煤成熟度的升高,燃烧排放的soot颗粒的芳香性逐渐增强,含O、N等不稳定结构逐渐减少。含硫化合物是燃煤排放soot颗粒的特征化合物,主要存在于高成熟度燃煤排放的soot颗粒中。这些结果对于了解不同成熟度的燃煤排放soot颗粒样品中分子结构和组成具有重要的意义。 |

In this study, the chemical properties of soot particles emitted from the combustion of household honeycomb coal of different maturities were studied using the pyrolysis gas chromatography/mass spectrometry (Py-GC/MS) technique. The influence of coal maturity on the pyrolysis products of soot was investigated. The results showed that the pyrolysis products derived from soot particles emitted from coal of different maturities were very similar, including aromatic compounds (58.1%-92.0%), phenolic compounds (0.66%-32.3%), aliphatic hydrocarbon (0.21%-9.57%), furan compounds (1.42%-2.57%), S-containing compounds (NA-4.12%) and N-containing compounds (NA-3.91%). They were all dominated by aromatic compounds, indicating the soot particles were characterized by aromatic nuclei and/or oxygen-and nitrogen-containing units. The results also showed that coal maturity has an important influence on the pyrolysis characteristics of soot particles. The aromatic compound content in the pyrolysis products increased with increasing coal maturity while the phenolic compound content showed a decreasing trend. The N-containing compounds were mainly in the soot samples emitted from the combustion of low maturity coal. These results indicated that the content of aromatic structures in soot samples increased and the labile O-and N-containing structures decreased with increasing coal maturity. The S-containing compounds were typical pyrolysates of coal combustion and mainly in soot samples emitted from the combustion of high maturity coal. These results are useful for understanding the molecular structures and compositions of soot materials emitted from the combustion of household coal of different maturity. |
