Outline of Final Research Achievements

The aims of this study was to develop a natural polymer-derived acid catalyst based on lignosulfonic acid, which is by-produced in the pulping waste liquid during chemical pulping process of woody biomass (sulfite pulping). It was revealed that lignosulfonic acid play a role as an efficient acid saccharification catalyst in the acid hydrolysis of woody biomass.

Academic Significance and Societal Importance of the Research Achievements

安価で入手容易なリグノスルホン酸が木質系バイオマスの酸糖化触媒として使用できる可能性を示したことで、バイオエタノール製造に必要なセルロース系バイオマスの糖化工程のコスト、エネルギー削減に大きな貢献が期待される。
