摘要
在原有工作基础上 ,采用毛细管气相色谱 /傅立叶变换红外光谱 -色谱保留指数 ( GC/ FTIR- RI)联合解析技术 ,研究了高温煤焦油重油馏分的化学组成。分别从重油馏分 F7( 30 0～ 330℃ )和 F8( 330～ 360℃ )中分离并鉴定出 70和 61种化合物 ,了解到不同配煤工艺对煤焦油组成与性能的影响 ,从而获得了一些有意义的结果 。
Capillary gas chromatography Fourier transform infrared spectrometry gas chromatography retention indices (GC/FTIR RI), combined with the linear relationship between retention value and boiling points for polycyclic aromatic hydrocarbons, performed the determination of the composition of heavy oil fractions in high temperature coal tar. More than 70 and 61 compounds were separated and identified in heavy oil fractions F 7(300 330 ℃) and F 8 (330 360 ℃) respectively. The results are useful in coal tar distillation processing and pollution monitoring when such compounds are present.
