The structure and carbonization behavior of the pitches from the products of gas-coking coal hydrogenation performed at 420ยฐC and 455ยฐC in a continuous bench scale unit were estimated. The pitches, prepared as residues from vacuum distillation of purified hydrogenation products, were characterized b
