Abstract
The effects of the surfactants on the impregnation performance of coal tar pitch are studied in this paper. The results show that the softening point and viscosity of the pitch are significantly decreased by modified with surfactants. These characters are helpful for the impregnation, although the carbon yield decreases slightly. The modifying mechanisms of surfactants on coal tar pitch are also discussed.
