| Outline of Final Research Achievements |
As efficient biomass utilization methods, a mild lignin solubilization method, an evaluation method of lignin-resin material, and a valuable chemical production from glucose were examined. The hydrophobic polymer of lignin was impregnated with dilute ethanol which contained the catalyst, so that the catalyst easily could access to the active sites. Thus infused catalyst promoted the depolymerization and prevented the re-condensation, and lignin was successfully depolymerized under the mild condition. The evaluation method of lignin as high performance resin material was also developed through some kinds of thermal analyses. Glucose was converted into HMF, which is one of the very valuable chemicals. A significantly high space time yield was achieved under an easy simultaneous reaction-extraction system which was realized using a microreactor.
