Method for manufacturing monosaccharides, oligosaccharides, and furfurals from biomass

摘要

Provided is a method for efficiently manufacturing monosaccharides, oligosaccharides, and furfurals from biomass. While continuously supplying an aqueous biomass suspension via a supply port of a continuous primary hydrolysis device and moving said biomass suspension through said device, the biomass is hydrolyzed under pressurization and heating conditions under which monosaccharides, oligosaccharides, and furfurals are produced. One resulting liquid is continuously discharged from a discharge port on the continuous primary hydrolysis device, and a resulting liquid containing monosaccharides, oligosaccharides, and furfurals is extracted from an intermediate extraction port provided at any point between the supply port of the continuous primary hydrolysis device and the discharge port thereof. The extracted liquid is subjected to a secondary hydrolysis process.
