Four lines of furfural extract oil from SINOPEC Maoming branch company was used as raw material , six extractants , including diethylene glycol , triethylene glycol , tetraethylene glycol , PEG 200 , PEG 400 and sulfolane were used to study the extraction desulfurization and denitrification ,among which PEG 200 was the best extractant .With PEG 200 as extractant , the effects of the extraction conditions on the desulfurization and denitrification of four lines of furfural extract oil were investigated , as well as the extraction performances of 2‐step and 3‐step extraction . The results showed that with PEG 200 as extractant , good removal results for thiophene and quinoline of the furfural extract oil were obtained . The suitable extraction conditions were the extraction time of 15 min , ultrasonic action of 10 min , extraction temperature of 60℃ and the volume ratio of solvent to oil 1 .
