Abstract: "The authors have recently proposed a novel degradative solvent extraction method that upgrades and fractionates various types of low-rank coals or biomass wastes into several different molecular weight fractions at around 350 °C. The lowest molecular weight fraction that was recovered as solid (termed soluble) by the yield of 19.4−71.7 wt % on a carbon basis had unique and almost raw-material-independent properties: almost free from ash and moisture, average molecular weight of around 300, carbon content of as high as 81.5−84.8 wt %, and oxygen content of as low as 6.5−12.1 wt %.
