Coal extraction behaviors on heating by high-temperature filtrations were investigated using the in-situ high temperature ^1H-NMR. The phase transformation of coal molecule were monitored by classifying to immobile (solid) component, intermediate component and mobile (liquid-like) component by ^1H-NMR relaxation measurement. Coal extraction yield was increased with increase in the extraction temperature, and suddenly decreased at higher temperature than 650 K approximately. That phenomenon was also traced as the formation and deformation of the liquid-like component and influenced by not only quantity but also quality of the component. The remaining amounts of the solid components were far smaller than those of filtration residues. Most of the intermediate component might fill up the gap. The molecular weight distribution of filtration residue was measured using TOFMS. There appealed no large differences even thought the amounts of solid components were different in three kinds of bituminous coals used in this study.
