Abstract
The effect of hydrothermal dewatering (HTD) on the structure of Loy Yang coal has been investigated by quantitative solid state C-13 and in situ broadline H-1 NMR, Treatment at 320 degrees C gives rise to significant decrease in aliphatic and CO/COOH functionality due to volatilization and thermal decomposition of the guest phase. Broadline H-1 NMR indicated that most of the hydrogen in the brown coal is relatively mobile (ca. 90%). However, after treatment, only 30% of the hydrogen remains so.
