The effects of various extractants on removal of aromatics of naphtha derived from the hydrogenation fraction of low temperature coal tar(coal-derived naphtha) were investigated at certain extraction temperature, extraction time, phase separation time and single stage extractant oil volume ratio of 40 ℃,5 min,20 min,1.5 ,respectively. The result showed that the dimethyl suifoxide containing 10 volume fraction N, N-dimethyformamid (V(DMSO):V(DMF)=9:1) regarded as a mixed solvent could obtain better aromatics removal rate. Then the effects of process conditions on liquid-liquid extraction aromatic were explored based on DMSO-DMF using single-factor tests and response surface methodology. The optimized process conditions were found as: extraction temperature of 44.48 ℃,extraction time of 5.30 min, single stage extractant oil volume ratio of 1.69 and phase separation time of 10 min. After five stages counter-current extraction under above process conditions, the aromatics removal rate is 89.51±0.03% and the yield of solvent oil is（73.33±0.03）%。
