Abstract
The purpose of this study was to establish and contribute to putting into practical use the technology that converts high-quality upgraded dehydrated biomass (UDB) to gas with high calorific value using a pyrolytic gasifier. The pyrolytic gasifier consists of separate pyrolyzing and combusting sections after dehydrating and deoxidizing biomass with high moisture using the technology of upgrading in oil, which is the technology proven for dehydrating brown coal. Among these processes, our institute took responsibility for elucidating and modeling gasification reaction of UDB, predicting the performance through numerical analysis of a gasifier, and studying the optimum system for the entire system including gas engine generators as well as evaluating its costs.
