摘要
The different carbon mesophase precursors as coal tar and petroleum pitches were analyzed for studying the mesophase formation. The influence of precursors characteristics, processing parameters (temperature, heating rate) on the development of mesophase stage was analysed. Raw materials were characterized from physico-chemical point of view (softening point, benzene insoluble fraction etc). The mesophase samples were characterized by optical, electronic microscopy (SEM), AFM and XRD and the coke yield were calculated.
