The Colloidal Characteristics of Blended Crudes

摘要

Iran and Saudi crude oils were selected to be studied in this article. The characteristics of colloid were investigated at the optimum active status (the distillation yield is higher than the theoretical distillation yield). The experimental results show that at optimized blending ratio, vacuum residue becomes denser, the precipitation point of vacuum residue advances, and the aggregation of colloidal particles becomes strong. It was found that the interaction of the functional groups after blending was similar to previous blending. However, at the optimized blending ratio the signals of hydrogen bond and condensed aromatic rings weakened.
