Additive effects of hydrogen donor on fluidity of non-or slightly-caking coal

Abstract

The decrease of caking property of blended coal (caking coal plus non-or slightly-caking coal) is a problem because the oxygen-containing functional groups in non- or slightly-caking coal catch hydrogen in caking coal. Therefore, the authors carried out hydrogenation of coal tar pitch (CP) and discussed the additive effects of the hydrogenated CP on fluidity of non- or slightly-caking coal. In this study, hydrogenation of fluoranthene (FL) was carried out at lower temperature and the additive effects of the hydrogenated FL on fluidity of several kinds of coals were estimated from the amount of transferable hydrogen in the hydrogenated FL.
