| Outline of Final Research Achievements |
Replacing fossil fuels with biomass energies leads to reduction of CO2 emissions because of its carbon neutral feature. Carbonization is essential to efficently utilize biomass, and therefore a rapid carbonization process using heat storage materials has been proposed and waste heats are focused on as a heat sources of the process. This study aimed at improvement of heat storage materials and verification of the process validity.
Fe-Mn-C alloy gave a large heat storage capacity. Its transformation temperature can be controlled by composition of Mn and C, and therefore it can be applied to a wide temperature range of waste gas. Simultaneous carbonization and pulverization process resulted in rapid heating of biomass and reduction of the time to produce the biomass char compared to conventional carbonization processes. Further, pulverization mechanism of this process was examined by a simulation applying DEM.
