采用同步荧光光谱法监测了液相色谱法以氧化铝作固定相将重质油中的芳烃按芳环数分离的分离过程。在同步荧光光谱的监测下，选择了液相色谱分离的合适进样量和分段梯度洗脱溶剂强度，使得减压馏分油和减压渣油中的芳烃都可较好地按芳环数进行分离。
Synchronous fluorescence spectrometry was used to monitor the separation of aromatics in heavy oil by aromatic ring using liquid chromatography with alumina as the stationary phase. Under the monitoring of synchronous fluorescence spectroscopy, the appropriate injection volume and the gradient of the elution gradient of the solvent were selected so that both the aromatic hydrocarbons in the vacuum distillate and the vacuum residue could be separated by the number of aromatic rings For separation.
