Application of biodiesel as an additive could depend less on the light oil in viscosity-reducing techniques for heavy oil. This paper describes the effects of addition of biodiesel on the heavy oil viscosity. The results indicate that moderate amount of biodiesel provides favorable effects on the viscosity reduction, which is superior to that of diesel. The origin of the viscosity reduction was confirmed by the FTIR spectra of the heavy oil mixed with biodiesel or diesel. The replacement of the hydrogen bonds in heavy crude oil could dissociate the aggregates of the asphalt and resin, which weakened the interaction between asphalt and resin and thus reduced the viscosity. With the increase of biodiesel added, the effect of polarity increased and the viscosity further reduced; while the added amount of biodiesel exceeded 15%, the role of polarity in the viscosity reduction was not obvious.
