The positive- and negative-ion electrospray ionization (ESI) coupled with Fourier transform-ion cyclotron resonance mass spectrometry (FT-ICR MS) was employed to identify the chemical composition of heteroatomic compounds in four distillates of Fushun shale oil, and their catalytic cracking performance was investigated. There are nine classes of basic nitrogen compounds (BNCs) and eleven classes of non-basic heteroatomic compounds (NBHCs) in the different distillates. The dominant BNCs are mainly basic N1 class species. The dominant NBHCs are mainly acidic O2 and O1 class species in the 300–350 °C, 350–400 °C, and 400–450 °C distillates, while the neutral N1, N1O1 and N2 compounds become relatively abundant in the > 450 °C fraction. The basic N1 compounds and acidic O1 and O2 compounds are separated into different distillates by the degree of alkylation (different carbon number) but not by aromaticity (different double-bond equivalent values). The basic N1O1 and N2 class species and neutral N1 and N2 class species are separated into different distillates by the degrees of both alkylation and aromaticity. After the catalytic cracking of Fushun shale oil, the classes of BNCs in the liquid products remain unchanged, while the classes and relative abundances of NBHCs vary significantly.

利用正离子和负离子电喷雾电离（ESI）结合傅里叶变换离子回旋共振质谱（FT-ICR MS）鉴定抚顺页岩油的四个馏出物中的杂原子化合物的化学组成及其催化裂化性能进行了调查。在不同的馏出物中，有九类碱性氮化合物（BNC）和十一类非碱性杂原子化合物（NBHCs）。优势BNC主要是基本的N1类物种。在300-350°C，350-400°C和400-450°C馏出物中，主要的NBHCs主要是酸性O2和O1类物质，而中性N1，N1O1和N2化合物在> 450°C时相对丰富。 C分数。碱性的N1化合物以及酸性的O1和O2化合物通过烷基化程度（不同的碳原子数）而不是通过芳香性（不同的双键当量值）分离为不同的馏出物。通过烷基化和芳族化的程度将基本的N1O1和N2类物质以及中性的N1和N2类物质分为不同的馏出物。抚顺页岩油催化裂化后，液体产品中的BNCs种类保持不变，而NBHCs的种类和相对丰度却相差很大。
