Outline of Final Research Achievements

Carbonation of biomass is environmentally sound and sustainable process for renewable energy resource production if external heat energy for carbonation can be extremely reduced. We found out the new method for torrefaction process by using microbial and oxidative spontaneous heat generation. As results of our determination, torrefaction can be conducted at extremely low temperature. Additionally our numerical analysis demonstrated that the carbonization process of practical scale was feasible by using insulated wall of the facility.
