Abstract:
1. An organic material production system using biomass material, the organic material production system comprising: a hydrothermal decomposition apparatus that causes the biomass material and 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 a biomass solid residue; an enzymatic saccharification device that treats, with an enzyme, cellulose in the biomass solid residue discharged from the hydrothermal decomposition apparatus, so as to enzymatically saccharify the cellulose to a first sugar solution containing hexose; a first fermenter that produces, using the first sugar solution obtained by the first enzymatic saccharification device, any one of alcohols, substitutes for petroleum, or amino acids by fermentation; a sulfuric acid decomposition device that decomposes, with sulfuric acid, the hemicellulose component in hot water discharged from the hydrothermal decomposition apparatus, so as to decompose the hemicellulose component to a second sugar solution containing pentose; and a second fermenter that produces, using the second sugar solution obtained by the sulfuric acid decomposition device, any one of alcohols, substitutes for petroleum, or amino acids by fermentation, wherein the hydrothermal decomposition device has a reaction temperature ranging from 180° C. to 240° C. and has a condition of hot compressed water, and wherein the sulfuric acid decomposition device has a decomposition temperature ranging from 100° C. to 140° C.
