Cellulose or hemicellulose hydrolysis catalyst, and a manufacturing method using the sugar-containing catalyst
2010
Object of the present invention are: to provide a novel catalyst for hydrolysis of cellulose, which was used without a large amount of sulfuric acid during the preparation of the catalyst, and there is no possibility of sulfuric acid eluted from the catalyst; not provide an even in hot water the new structure of cellulose hydrolysis and vary the catalyst activity is reduced; and a method for producing a cellulose hydrolyzate glucose as the center to provide a use of these catalysts. The present invention provides a cellulose hydrolysis catalyst, the catalyst comprising a porous carbon material, porous carbon material having 800m2 / g or more 2500m2 / g or less and having a specific surface area of 100mmol / kg or more 700mmol / kg or less of phenolic hydroxyl the amount of the porous carbon material, for example, a porous carbon material having a shape of a mesoporous silica template to the mesoporous silica obtained carbon-filled pores; the present invention also provides a cellulosic or hemicellulose hydrolysis with a catalyst carrying a group 8 to 11 transition metal in the porous carbon material.
