We investigated the influence of various reagents on the liquidity of coal to improve the fluidity of low grade coal. A low fluidity coal and reagents including amine type aromatic and oxygen-containing aromatic were mixed so that the reagents mass ratio was 10 mass%. The mixed sample was charged in a vessel for measuring the fluidity and heated to a re-solidification temperature at 3 °C/min to measure the maximum fluidity and the softening temperature range. Among the added reagents, it was found that addition of oxygenated aromatic compounds deteriorated the fluidity of coal. On the other hand, improvement of fluidity was observed at the time of addition of amine type aromatic. Among these, it was confirmed that the softening initiation temperature of coal was greatly shifted to the low temperature side when phenothiazine was added, and the maximum fluidity was greatly improved.
