This paper studies the transformation of the carbon framework of coal tar pitch in the process of thermolysis in the presence of carbon additives of different structures. It is established that as a result of the application of all investigated carbon additives, the content of volatile products released as a result of the thermolysis of the ash, including carcinogenic compounds, decreases, which contributes to the increase of the coke residue yield. The highest yield of coke residue was found when using nanostructured carbon materials as an additive, but the structure of the resulting carbon material is more disordered than in the case of individual pitch. It is shown that the use of such additives promotes the formation of graphite-like structures in the process of thermolysis of pitch and to a greater extent than amorphous carbon additives, reduces the amount of carcinogenic volatile products of coal tar pitch thermolysis.
