- W1509454868 abstract "Supercritical water extractions were performed on low-rank coals utilizing a semicontinuous supercritical solvent extraction system. Percent conversions ranged from 40 to 50% while extract yields ranged from 10 to 30% at 380/sup 0/C. The conversions and extract yields increased with increasing operating temperature and pressure. The conversions also decreased with increasing coal rank and correlated well with the percent volatile matter in the coals. Organic analyses of the resulting extracts have included separations into pentane, methylene chloride and methanol soluble fractions by short column chromatography, 200 MHz proton NMR, IR spectroscopy and capillary gas chromatography. Proximate and ultimate analyses indicated that supercritical water extracts the volatile, hydrogen-rich fraction of the coal. Organic analyses show that the extract is highly polar in nature with significant quantities of phenols and long-chain aliphatic fatty acids. 11 refs., 5 figs., 5 tabs." @default.
