On the coking process of caking coal, excess addition of non- or slightly- caking coal decreased the caking properties of coal because the oxygen-containing functional groups in non- or slightly- caking coal caught hydrogen in caking coal. The authors have reported that fluidity of three kinds of non- or slightly- caking coals increased by addition of either hydrogenated coal tar pitch (CP) or hydrogenated fluoranthene. In this study, after hydrogenation of three kinds of the CP related model compounds (pyrene, phenanthrene, perylene), additive effects of the hydroaromatic compounds upon enhancement of caking properties of non- of slightly- caking coal were discussed.
