Liquidization of wet biomass (cabbage) was conducted at 423-473 K and 1.2-1.3MPa. From observation with electron microscope and analysis of components, it was found that liquidization was caused by the breakdown of cell structure, mainly decomposition of hemicellulose. Liquidized product was slurry liquid, which could be described as a Newtonian fluid. The higher the temperature for liquidization treatment was, the lower the apparent viscosity of liquidized product was. It was also confirmed that gasification in supercritical water (673K, 25MPa) was promoted by liquidization treatment at 423 K.
