摘　　要：应用生物表面活性剂烷基糖苷在室温下对石油进行增溶,分别考察了溶液pH和无机盐浓度变化对石油溶解效果的影响,并通过正交实验验证确定最佳条件。结果表明,烷基糖苷溶液在浓度超过临界胶束浓度时,表现出明显的增溶特性,其质量增溶比约为0.013;溶液浓度、pH和无机盐浓度变化均能显著影响增溶作用。实验条件下得到烷基糖苷增溶石油的最佳条件为:烷基糖苷浓度39.00 g/L,pH为5,无机盐浓度0.5 mol/L,得到最大溶油量3.99 g/L。Solubilization of crude oil at room temperature by alkyl polyglucoside biosurfactant was studied, the effect of solution pH and salinity on surface activity and solubilization capacity was investigated, and the optimal conditions were also determined by using orthogonal experiment. The results indicated that alkyl polyglucoside showed significant solubilization properties at concentration above its CMC, with a weight solubilization ratio （WSR） of 0.013. The enhanced solubilization of crude oil changed obviously with the change of solution concentration, pH and salinity. The predicted optimal conditions were about 39.00 g/L of alkyl polyglucoside, pH 5, 0.5 mol/L NaCl, while a maximum amount of 3.99 g/L was obtained.
