PLANT-BIOMASS HYDROLYSIS METHOD

摘要

The present invention pertains to a plant-biomass hydrolysis method characterized in that a hydrothermal treatment is performed in the presence of an equivalent concentration of an acid equal to 30-1,000% of the equivalent concentration of cations in a plant-biomass hydrolysis reaction solution. The present invention also pertains to a glucose manufacturing method using the aforementioned hydrolysis method. The aforementioned hydrothermal treatment is preferably performed using an inorganic acid as the abovementioned acid and using a solid catalyst comprising a carbonaceous material. The present invention eliminates reaction-inhibiting factors, resulting in a high glucose yield.
