Abstract

See full text

A biomass hydrothermal decomposition apparatus that feeds a solid biomass material 11 from one side of an apparatus body 42, feeds pressurized hot water 15 from the other side, to hydrothermally decompose the biomass material 11 while bringing the biomass material 11 into counter contact with the pressurized hot water 15, dissolves hot-water soluble fractions in hot water, discharges the pressurized hot water to outside from the one side of the apparatus body 42 as a hot-water effluent 16, and discharges a biomass solid 17 to the outside from the other side. The biomass hydrothermal decomposition apparatus includes: an internal-temperature cooling unit that rapidly drops a temperature after performing hydrothermal decomposition for a certain period of time; temperature measuring units T1 to T8 that measure an internal temperature; and a controller 100 that controls an internal temperature to be maintained at a predetermined cooling temperature by the internal-temperature cooling unit based on temperature measurement results obtained by the temperature measuring units T1 to T8.
