Abstract
Heat treatment in hot-compressed water (hydrothermal treatment) at 250 °C upgrades woody biomass to solid with particular features by converting a major portion of carbohydrate (cellu- lose and hemicellulose) into water soluble matter and solvent-soluble lignin-like material, re- moving more than 90% of the alkali and alkaline earth metallic (AAEM) species. The upgrad- ed biomass is available in production of metallurgical coke that has mechanical strength high- er by more than six times than that of conversional one from coals, and activated carbon with specific surface area well above 2,000 m2 g -1 without any additives/chemicals. Repeated use of product water enables to maximize the yield of upgraded biomass, maintaining its ability of leaching of AAEM species.
