摘　　要：某炼油厂减二线NMP抽出油芳碳率高达51.84%,将此抽出油利用糠醛单溶剂再抽提,剂油比为3时重相油中芳烃质量百分含量在90%以上,芳碳率在70%以上,满足高芳烃油芳烃含量要求。利用糠醛+石油醚再抽提此抽出油效果比单用糠醛更好,在减二抽:糠醛∶石油醚=1∶1∶1和减二抽∶糠醛∶石油醚=1∶1∶2时,重相油中芳烃质量百分含量均在90%以上,芳碳率分别为74.65%和85.60%;重相油中糠醛含量比糠醛∶减二抽=3时少,蒸出溶剂耗能耗时较少。双溶剂处理后轻相油裂化性能均较处理前优化明显,在减二抽:糠醛∶石油醚=1∶1∶1时裂化性能更佳。Aromatic carbon rate of second vacuum side NMP extract oil in a refinery is high as 5 1 .84%,and after being extracted with furfural solvent when the rate of solvent and oil is 3∶1 ,the arene content in heavy oil becomes over 90%,which meets the standard of high aromatic oil.It could be more effective with furfural plus petroleum e-ther extraction,when second vacuum side∶furfural∶petroleum ether=1∶1∶1 or second vacuum side∶furfural∶petrole-um ether=1∶1∶2,aromatic rate are 74.65%and 85.60%respectively.When furfural：second vacuum side =3, it costs less time and less energy to evaporate the solvent.Light oil cracking is obviously improved with furfural plus petroleum ether solvent and cracking performance is perfect when second vacuum side∶furfural∶petroleum ether=1∶1∶1 .
