Chemical micronization of woody biomass using the microwave

As a basic study for the new materialization of biomass, the chemical dispersion of bio-mass using microwave was performed under various conditions. And the characteristics of dispersed residues were compared with various conditions. According to the reaction condition of microwave, the residual ratio by chemical micronization of wood meals was decreased, and Klason lignin of residues were also decreased. However, the content of acid soluble lignin did not show any significant difference. These results indicate that the chemical dispersion reaction using microwave showed the lowest residual lignin content at 60 seconds of reaction time and 2.5% of the catalyst condition or at 120 seconds and 2.0%. It is expected that the residual ratio and the residual lignin content can be controlled by the catalyst content and reaction time in the chemical micronization.
