Outline of Final Research Achievements

Inhibition of the formation of solid carbonized substances during secondary degradation reactions would be quite effective for production of useful chemicals from biomass through pyrolysis. Cellulose is a composite material consisting of the crystallites with the diameter of ~10nm and decomposes from the surface of the crystallites in pyrolysis. In this study, aromatic solvents having polar substituents were found to penetrate into the space between crystallites effectively and control the secondary degradation reactions against complex carbonization reactions, which results in the effective production of levoglucosan and 5-HMF as useful chemicals. In addition, cellulose carbonization mechanism via 5-HMF was newly proposed.
