ABSTRACT

Pyrolyzed fuel oil (PFO) and coal tar was blended in the feedstock to produce pitch via ther\-mal reaction. The blended feedstock and produced pitch were characterized to investigate the effect of the blending ratio. In the feedstock analysis, coal tar exhibited a distinct distri\-bution in its boiling point related to the number of aromatic rings and showed higher Con\-radson carbon residue and aromaticity values of 26.6% and 0.67%, respectively, compared with PFO. The pitch yield changed with the blending ratio, while the softening point of the produced pitch was determined by the PFO ratio in the blends. On the other hand, the carbon yield increased with increasing coal tar ratio in the blends. This phenomenon indicated that the formation of aliphatic bridges in PFO may occur during the thermal reaction, resulting in an increased softening point. In addition, it was confirmed that the molecular weight dis\-tribution of the produced pitch was associated with the predominant feedstock in the blend.
