通过蒸馏方法将生物质热解油（BPO ）精制后与柴油配制成乳化燃料，研究了影响乳化燃料稳定性的因素，结果表明，乳化燃料的稳定性与复合乳化剂HLB值和乳化温度有关，乳化剂的最佳 HLB值在7左右，乳化燃料的稳定性随乳化温度的提高先增大再减小，40℃时乳化燃料的稳定性最好。理化分析表明乳化油的密度、运动黏度、凝点等物理性质基本能够达到车用燃料标准。采用激光衍射技术对乳化燃料喷雾特性进行了研究，结果表明，随着生物质热解油乳化比例的增加，喷雾锥角先减小后增大，Sauter平均直径 D32逐渐增大，雾化质量逐渐变差。

The emulsified fuel was prepared by mixing diesel with the refined bio-pyrolysate oil (BPO) with distilling method and the influencing factors of its stabilization were researched .It was found that the stabilization of emulsified fuel was relevant to HLB value of compound emulsifier and emulsified temperature .The optimal HLB value of emulsifier was about 7 .The sta-bilization of emulsion fuel first increased and then decreased with the increase of emulsified temperature and the optimal temper-ature for good stability is 40 ℃ .The physical and chemical analysis showed that the physical property such as density ,kine-matical viscosity ,condensation point and etc could meet the standards of vehicle fuel .In addition ,the spray characteristics of e-mulsified fuel were tested by the laser diffraction technology .The results showed that the spray cone angle first decreased and then increased ,the Sauter mean diameter D32 increased gradually and the atomization quality became worse with the increase of BPO proportion .
