Carbonization of petroleum and coal tar pitches to toluene insoluble fraction (77) was investigated under air and nitrogen gas blowing systems. The TIyield was evaluated on the basis of the weight of pitch loaded. Changes of the yield with the reaction time were analyzed by a kinetic model of carbon
A QI-free coal tar pitch with a softening point around 80Β°C was air blown in an autoclave at 330", 360", and 38O"C, respectively, for various periods in order to prepare a pitch precursor for GPCF. Air blowing markedly increased the softening point and contents of solvent insoluble fractions such as
