摘要
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 (SFS) was used to monitor the procedure of separating aromatics according to aromatic ring number in heavy petroleum fractions by liquid chromatography with alumina as stationary phase. The proper sample load and stepwise gradient of the solvent strenth for the liquid chromatographic separation were selected under the monitoring of SFS. With the selected separation condition the aromatics in vacuum gas oil or vacuum residue were successfully separated into fractions with different aromatic ring number. Above results provided a base for the preparative separation of aromatics by ring number in heavy petroleum fractions.
