摘　　要：柴油中芳烃的质量分数与油品质量密切相关,脱除其中芳烃可以改善油品质量,提高柴油十六烷值。以糠醛为溶剂对柴油中的芳烃进行萃取,并借助超声波对萃取的辅助作用,研究萃取温度、剂油比、萃取时间、超声波功率、加盐、萃取级数等因素对芳烃萃取效果的影响。实验结果表明,在超声功率为200 W,剂油比为4∶1,温度为40℃,萃取时间为30 min时,芳烃萃取分离的效果最佳,萃取剂中加盐及采用多级萃取有利于芳烃萃取分离。The aromatic content in the diesel is closely related to its quality. Refining the oil can improve both the quality and the octane number of the diesel. Using the furfural as solvent,ultrasonic extraction of aromatic from the diesel is performed. The effects of extraction temperature,extraction time,ratio of sovent to oil,ultrasonic power,added salts and extraction series are also studied. The best extraction effect of aromatic can be achieved under the following conditions：200 W of the ultrasonic power,4 ∶ 1 of the solvent to oil ratio,40℃ of extraction temperature and 30 minutes of the extraction time. The addition of salt to the extraction solvent and the empolyment of multi-stage extraction are in favor of aromatics extraction.
