| 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.
