加氢尾油中多环芳烃存在形态及其含量的GC-MS分析

Analysis of forms polycylic aromatic hydrocarbons in residual oil from hydrocraking unit by GC-MS

本文利用GC-MS法对加氢尾油中芳烃的存在形态进行了研究,并进行了定量分析。结果表明,利用GC-MS法对加氢尾油中多环芳烃进行分析,具有选择性高,响应呈线性,芳烃组分信号不受烷烃干扰,分析时间短和精密度好等优点。

The forms of polycylic aromatic hydrocarbons in residual oil from hydrocraking unit were studied and quantitatively analysed by gas chromatography combined with mass spectrometry in this paper (GC-MS). The results showed that the GC-MS had the advantages of high selectivity, rapid analysis, high precision, good linear response, and low interference on PAH signals, etc.
