Abstract
Transmission electron micrographs obtained with the freeze-fracture re plication technique on three typical Chinese vacuum residues and their fractions demonstrate that petroleum vacuum residues are colloidal sy stems, in which asphaltenes (the n-heptane-insoluble, toluene-soluble fraction) and heavier resins constitute the dispersed phases and the r emaining lighter resins, aromatics and saturates the dispersing media.
