摘要
以非离子表面活性剂Tween80和Span80复合成实验用乳化剂乳化180#燃料油,考察了复合乳化剂HLB值和添加量与油包水型乳化燃料油稳定性、粘度、分散相粒径的关系,以及掺水量对乳化燃料油残炭和热值的影响。结果表明,随复合乳化剂HLB值从6增加到10,油包水型乳化油的稳定性和粘度降低,而分散相平均粒径增加;随复合乳化剂添加量增加,乳化油的稳定性和粘度增加,分散相的平均粒径减少;当复合乳化剂添加量一定时,随掺水量增加,乳化燃料油的热值和残炭值均降低;乳化后,单位质量乳化燃料油的热值增加。
Fuel oil 180° was emulsified by the mixed emulsifier of Tween80 and Span80. Effects of the HLB value and dosage of the mixed emulsifier on the stability, viscosity and dispersed particle size of the emulsions were investigated, and effects of the mixed emulsifier and the amount of added water on the residual carbon and the heat value of the emulsions were also investigated. The experimental results showed that the stability and the viscosity of the water- in- fuel oil emulsions decreased as the HLB value of the mixed emulsifier increased from 6 to 10, however, their dispersed particle size increased; and the stability and the viscosity of the water-in-fuel oil emulsions increased as the mixed emulsifier dosage increased, however, their dispersed particle size decreased. The heat value and the residual carbon of the emulsions decreased as the amount of added water increased, while the mixed emulsifier dosage unchanged. Compared with fuel oil 180° , the heat value of the oil with the per unit mass in the emulsions increased.
