摘　　要：以乳化液稳定性为评价指标，研究了复配乳化剂、助乳化剂、助乳化剂与复配乳化剂质量比[m（C／m（T）]及生物质裂解油在乳化液中质量分数的选择，并考察了HLB值、乳化温度、乳化时间、乳化方式、搅拌方式对乳化液稳定性的影响。实验结果表明：采用质量分数1．7％的T-5和乳化剂A的复配乳化剂，m（C）／m（T）为0．05的正辛醇为助乳化剂，在HLB值为8、乳化温度为20～40℃的条件下，将质量分数5％的生物质裂解油在柴油中高速乳化5min，其中，乳化方式为T-85溶于生物质裂解油，乳化剂A溶于柴油，边搅拌柴油边加入生物质裂解油，再加入助乳化剂，乳化液的稳定性较好，稳定时间可达20d。With emulsion stability as the evaluation index, the selections of combined surfactants,cosurfactants,the ratio of cosurfactants and combined surfactants, the mass fraction of biomass pyrolysis oil in emulsion are researched. The effects of HLB value, emulsifying temperature, emulsifying time, emulsifying method, and stirring method on the emulsion stability are investigated. The optimal reaction conditions are as follows： 1.7% of combined surfactants of T-85 and Surfactant A, n-octanol with m （C）/m （ T ） = 0. 05 as cosurfactant, HLB value of 8, emulsifying temperature of 20 - 40 ℃, 5% of biomass pyrolysis oil added into diesel oil,5 min of high-speed emulsification. Emulsifying method is that T-85 is dissolved in biomass pyrolysis oil and emulsifier A is dissolved in diesel oil, then biomass pyrolysis oil is added into diesel oil with stirring,finally the cosurfactant is added. At the optimal conditions,the stability time of emulsion can last for 20 davs.
