Abstract
A biomass hydrothermal decomposition apparatus includes, a biomass feeder () that feeds biomass material () under normal pressure to under increased pressure, a hydrothermal decomposition device (A) that allows the fed biomass material () to be gradually moved inside a gradient device main body () from a lower end thereof with a conveyor screw (), and also allows hot compressed water () to be fed from an other end of a feed section () for the biomass material into the main body (), so as to cause the biomass material () and the hot compressed water () to countercurrently contact with each other and undergo hydrothermal decomposition, and that transfers a lignin component and a hemicellulose component into the hot compressed water, so as to separate the lignin component and the hemicellulose component from the biomass material (); and a biomass discharger () that discharges, from the upper end of the device main body (), a biomass solid residue () under increased pressure to an under normal pressure.
