中文摘要	探索了碱木质素经H2O2预处理,再经磺化、胺化、烷基化合成驱油用表面活性剂的方法。首先考察了过氧化氢预处理条件对表面张力的影响。结果表明,当过氧化氢与碱木质素质量比为1∶10,温度70℃,处理时间30 min效果较好,经该条件预处理后合成的表面活性剂质量分数为0.9%时,表面张力降至24 mN/m。进一步考察碱、表面活性剂质量分数对孤岛原油油/水界面张力的影响,并与同条件下未经预处理合成的表面活性剂的油/水界面张力对比,结果表明,碱木质素经预处理合成的表面活性剂质量分数为0.4%时,与质量分数为0.4%NaOH复配后可使最低油/水界面张力达0.07 mN/m,较未经氧化预处理组稳定时间明显延长。红外光谱(FT-IR)分析表明了碱木质素改性前后结构的变化。; The method for synthesis of surfactants for enhanced oil recovery,including pretreatment with H2O2,sulfonation, amination and alkylation,was studied with alkali lignin as feedstock. Firstly,the effects of pretreatment conditions on surface tension were investigated. The suitable pretreatment conditions were that mass ratio of H2O2to alkali lignin was 1 ∶ 10 at 70 ℃ for 30 min. Under the pretreatment conditions,the surface tension of 0. 9 % surfactant solution could be reduced to 24 mN / m. The effects of surfactant and alkali concentration on oil-water interfacial tension of Gudao crude oil were also studied. The results showed that when both the surfactant concentration and NaOH concentration was 0. 4 %,the oil-water interfacial tension was decreased to 0. 07 mN / m. It was more stable than the control surfactants synthesized without H2O2pretreatment. Finally,Fourier Transform Infrared( FT-IR) analysis indicated the structural characterization of lignin before and after modification.
