<p><P>PROBLEM TO BE SOLVED: To provide a method for producing saccharides and a solid fuel from biomass with high efficiency and low energy. <P>SOLUTION: The method for producing the saccharides or the solid fuel from the biomass as a raw material comprises the following steps. a slurry concentration increasing step of preparing a low-concentration slurry in which the biomass is suspended in high-pressure water heated at 100-250°C, further adding the biomass to the slurry and preparing a high-concentration slurry, a hydrolyzing step of heating the high-concentration slurry at 250-350°C, increasing the pressure to not lower than the vapor pressure of water at the temperature, degrading the biomass and producing the saccharides, a cooling step of cooling the high-concentration slurry passing through the hydrolyzing step, a recovering step of recovering an aqueous solution from the high-concentration slurry cooled in the cooling step and a recovering step of separating the saccharides from the aqueous solution or recovering water-insoluble ingredients from the high-concentration slurry passing through the hydrolyzing step. The water-insoluble ingredients are dehydrated to produce the solid fuel. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
