摘要:
An alcohol production system that produces alcohol by alcoholic fermentation using a saccharide solution, including an alcoholic fermentation vessel in which the saccharide solution is fermented by adding yeast to produce alcohol, which is an organic feedstock, and a biomass-hydrothermally-treated-product adding means that adds a biomass hydrothermally-treated product obtained by hydrothermally treating a biomass feedstock to the alcoholic fermentation vessel. The alcohol production system can improve alcoholic fermentation efficiency and realize cost reduction without adding only a mineral salt from outside.

摘要:
A biomass hydrothermal decomposition apparatus that feeds a solid biomass material 11 from one side of an apparatus body 42, feeds 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 hot water 15, dissolves hot-water soluble fractions in hot water, discharges the hot water to outside from the one side of the apparatus body 42 as a hot-water effluent 16, and discharges a biomass solid (a hot water insoluble) 17 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 42, in which a feeding temperature of the hot water 15 (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.

A biomass hydrothermal decomposition apparatus includes, a biomass feeder (31) that feeds biomass material (11) under normal pressure to under increased pressure, a hydrothermal decomposition device (42A) that allows the fed biomass material (11) to be gradually moved inside a device main body (42A) from either end thereof in a consolidated condition, and also allows hot compressed water (15) to be fed from an other end of a feed section for the biomass material into the main body (42A), so as to cause the biomass material (11) and the hot compressed water (15) to countercurrently contact with each other and undergo hydrothermal decomposition, and that elutes 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 (11); and a biomass discharger (51) that discharges, from the side where the hot compressed water is fed into the device main body, a biomass solid residue (17) under increased pressure to under normal pressure.
