| Outline of Final Research Achievements |
To apply thermal gravimetric analysis (TGA) to the characterization of lignocellulosic biomasses, the sample preparation and analysis conditions were optimized. Tablets of approximately 4.5 mm in diameter were cast using a custom-made press machine, which allowed the reproducible measurement of flossy lignocellulosic samples. The fundamental data were obtained through the TGA technique developed to carry out measurements of pretreated lignocellulose such as Japanese cypress, Miscanthus sp., and various cellulose nanofibers. It was found that the derivative thermal gravimetric (DTG) curve is an indicator for characterization of lignocellulosic biomass through TGA data mining. Our results indicate that the DTG curve also has the potential to serve as the criterion for selecting the pretreatment technique for enzymatic hydrolysis and the preparation method of cellulose nanofibers from lignocellulose.
