Abstract Positive-ion electrospray ionization Fourier transform ion cyclotron resonance mass spectrometry (ESI FT-ICR MS) and gas chromatography-nitrogen chemiluminescence detection (GC-NCD) was used to study the effect of pyrolysis temperature (400℃, 430℃, 460℃, 490℃, and 520℃) on basic nitrogen compounds in Huadian shale oil. Because of the effect of secondary cracking, the relative contents of aliphatic amines and anilines decreased with increase in pyrolysis temperature. The relative abundances of N1 classes decreased first but later increased. The relative abundances of N2OX and N3OX increased first but later decreased, and reached the maximum at 460 °C, which were 21.47% and 5.27%, respectively. As the pyrolysis temperature increased, the relative abundance of the N1 classes within the carbon number ranged from 10 to 30 obviously increased. In conclusion, the pyrolysis temperature had an effect on the number, relative abundance, DBE distribution and carbon number distribution of heteroatom compounds in shale oil.

正离子 ESI FT-ICR MS 和 GC-NCD 热解温度对华甸页岩油碱性氮组分组成的影响

摘要 采用正离子电喷雾电离傅里叶变换离子回旋共振质谱（ESI FT-ICR MS）和气相色谱-氮化学发光检测（GC-NCD）研究热解温度（400℃、430℃、460℃）的影响。 、490℃和520℃)对华电页岩油中碱性氮化合物的影响。由于二次裂解的影响，脂肪胺和苯胺的相对含量随着裂解温度的升高而降低。N1类的相对丰度先下降后增加。N2OX和N3OX的相对丰度先升高后降低，在460℃时达到最大值，分别为21.47%和5.27%。随着热解温度的升高，碳数在10~30之间的N1类的相对丰度明显增加。
