摘　　要：页岩油的加工和利用越来越受到人们的重视。文章利用电喷雾-傅立叶变换离子回旋共振高分辨质谱仪(ESI FT-ICR MS)对抚顺页岩油中的氮化物进行了详细的表征。结果表明,抚顺页岩油中的碱性氮化物以N1类氮化物(化合物分子中含有1个氮原子)居多,N2类氮化物(分子中含有2个氮原子的化合物)次之。N1类碱性氮化物主要是带烷基侧链的吡啶类衍生物和带一个环烷环的吡啶类衍生物。N2类碱性氮化物则同时含有两个氮杂环,一个环为碱性环(含N六元环),而另一个为非碱性环(含N五元环)。Shale oil is attracting more and more attention as a very important substitutable fossil fuel resource. In the present research, the class and structure of nitrogen species in Fushun shale oil was characterized by Electrospray Ionization （ESI） Fourier Transform Ion Cyclotron Resonance Mass Spectrometry （FT-ICR MS）. The data indicated that N1 and N2 classes of basic nitrogen compounds were dominant in Fushun shale oil. N1 class species were mainly derivatives of pyridine with alkyl and cycloalkyl chains. N2 class species were likely composed with two rings. One was a pyridine ring and the other was a pyrrole one.
