No.40 Effect of Asphaltene Type on Degree of Asphaltene Aggregation

Abstract

Degree of asphaltene aggregation (D_<agg>) in various solvents were determined using Rayleigh scattering measurements. Structural analyses of three kinds of asphaltenes were conducted to clarify the effect of asphaltene type on the D_<agg>. The results indicated that general bulk analyses could not explain the difference in the D_<agg> behaviors.
