摘要

RARE METHOD OF HYDROLYTIC SACARIFICATION OF A CELLULOSIC BIOMASS WITH THE USE OF MULTIPLE PRESSURE CONTAINERS AND SYSTEM FOR HYDROLYTIC SACARIFICATION OF A CELLULOSIC BIOMASS CLEANING MULTIPLE PRESSURE CONTAINERS. To hydrolyze the cellulose and / or hemicellulose contained in a biomass into monosaccharides and oligosaccharides when using high temperature and high pressure water in a subcritical condition, it is provided that it is excellent in thermal efficiency and saccharide yields; When hydrolyzing cellulose or hemicellulose to saccharides when using high temperature, high pressure water in a sub-critical condition, a large amount of slurry is cooled in a condition below the sub-critical condition when exposing the slurry contained in a pressure vessel under a condition of high temperature and high pressure for momentary evaporation in a pressure vessel that is loaded with a slurry of cellulosic biomass and partially heated, in which it is possible to prevent the degradation of saccharides into organic acids or the like, as well as to save energy by recovering thermal energy; it is possible for the cellulosic biomass to be loaded into a water-permeable container and then the water-permeable container to be encapsulated in the pressure vessel along with the water.
