| Abstract: | Mesophase pitch (MP) was produced by heating coal tar pitch in a microautoclave furnace at various temperatures and residence times under nitrogen atmosphere. FTIR, Polarized Light Microscopy, XRD and SEM were employed to characterize MP, indicating that the coal tar pitch was transformed into MP through dehydrogenative condensation reactions. The optimum yield was found at 400℃ and 7h |
