Abstract: Furfural extraction oil, ethylene tar and vacuum residue were studied in this paper, the three kinds of oil were blended under laboratory conditions, the viscosities were determined on a certain temperature, and the causes of viscosity change were analyzed by using petroleum disperse system theory. The results show that, when the volume ratio of furfural extraction oil, ethylene tar to vacuum residue are 3∶5∶1, 1∶3∶1, 2∶5∶1 and 1∶5∶1, the viscosity, flash-point and stability are all up to the standard of marine fuel.

摘要：         以糠醛抽出油、乙烯焦油、减压渣油为研究对象，对三种油样进行调和，在一定温度下测定粘度。采用石油胶体分散体系理论分析变化原因。结果表明：当Ｖ（糠醛抽出油）∶Ｖ（乙烯焦油）∶Ｖ（减压渣油）分别为３∶５∶１、１∶３∶１、２∶５∶１、１∶５∶１时，调和燃料油的粘度、闪点、稳定性等指标符合船用燃料油标准。
