Abstract

The modifying activities of hydrogenated pyrene (HP) and its oxidized derivatives were examined in co-carbonization with solvent refined coal, solvent treated coal, a fusible and a non-fusible coal. The present additives all showed a significant activity, with HP oxidized at 150°C exhibiting the highest activity. The activity of the additive is discussed from its structural indices and coke yield in relation to its dissolving and hydrogen donating abilities. The modifying susceptivility of the carbonizing substance is rated in the order described above, being correlated with its single carbonization properties, such as fusibility and potential for anisotropic development. A consecutive treatment of partial hydrogenation and oxidation is emphasized as a useful technique for producing active additive and an excellent coking substance from the pitch material.
