Abstract
A biomass hydrothermal decomposition apparatus that feeds a solid biomass materialfrom one side of an apparatus body, feeds hot waterfrom the other side, to hydrothermally decompose the biomass materialwhile bringing the biomass materialinto counter contact with the hot water, dissolves hot-water soluble fractions in hot water, discharges the hot water to outside from the one side of the apparatus bodyas a hot-water effluent, and discharges a biomass solid (a hot water insoluble)to outside from the other side. The biomass hydrothermal decomposition apparatus includes an effective reaction region A formed from the other side to the one side of the apparatus body, in which a feeding temperature of the hot water(for example, 200° C.) is maintained for a predetermined period of time to cause hydrothermal decomposition, and a temperature drop region B in which a temperature is rapidly dropped to a temperature (for example, 140° C.) at which the hot-water soluble fractions are not excessively decomposed (for example, from 200° C. to 140° C.), immediately after it is out of the effective reaction region A.
