船用燃料油的调和技术及其稳定性研究

以渣油、乙烯焦油、页岩油为研究对象调和制备船用燃料油。考察了调和比、温度、不同亲水亲油平衡值(HLB值)及复配表面活性剂对调和油黏度的影响。结果表明，当m(渣油)/m(乙烯焦油) =1∶1.25和m(渣油)/m(页岩油)=1∶1.00时，得到的调和油不但黏度指标达到180#船舶燃料油产品要求，而且闪点和稳定性均符合国家标准；当添加HLB值为12且以阴离子与非离子表面活性剂复配的表面活性剂时，调和油的黏度显著降低。复配表面活性剂添加质量分数为0.3%时, 黏度降到最低。

Blending Technology and Study on the Stability of Marine Fuel

The marine fuel was prepared from residual oil,the ethylene tar and the shale oil.The effects of harmonic ratio,the temperature,different hydrophilic lipophilic balance（HLB） and the compound surfactants exchange on the oil viscosity were studied.The experiment results show that when the m（residue）/m（ethylene） =1∶1.25 and m（tar residue）/m（shale oil）=1∶1.00 blend oil not only viscosity at 180# marine fuel oil products indicator,and the flash point and stability are in line with national standards.When add HLB=12 with anionic and non-ionic surfactant blend oil viscosity significantly reduced.When compound surfactant added at 0.3 persent,the viscosity to a minimum.
