| Abstract
| - Mixtures of various pitches and granular carbons were pyrolyzed at 430 °C in order to studythe influence of different granular carbons on pitch pyrolysis behavior. The toluene-insolublecontent was used to monitor the degree of polymerization of the pitches during thermal treatment.The influence of the presence of granular carbons on mesophase development was studied byoptical microscopy. Important differences in the pyrolysis behavior of the pitches were observedwith the different granular carbons used. The differences were more pronounced for greenpetroleum coke and graphite. Green petroleum coke accelerated condensation and polymerizationreactions. Graphite, however, slowed polymerization of the pitch components, causing mesophaseto form and grow on the surface of the graphite particles.
