| Outline of Final Research Achievements |
The development of catalytic conversion from polysaccharides to useful chemicals is important for the sustainable society in future. In addition to cellulose, polysaccharides with abundant resources include mucopolysaccharides, which are the main components of seaweed. In this study, we investigated the conversion process of mucopolysaccharides and achieved molecular weight-selective hydrolysis with controlled sulfate group concentrations. In addition, the polysaccharide-concentration effects of near the surface of the sulfonated activated carbon catalyst on the hydrolysis of polysaccharides was clarified by comparing with strongly acidic cation exchange resins.
