Abstract
Fuel conversion of high moisture content biomass (sludge) was conducted in middle pressure steam at 473K and 1.8MPa by stirring the reactor. In this research, components of solid and gas products were analyzed in order to clarify the mechanism of this system scientifically. As a result, it was found that the calorific value of solid products increased after the treatment. And CO_2 production was promoted during the reaction. This result suggested that an endothermic reaction involving CO_2 production with middle pressure steam was promoted. It was also found that solid product's smell and volume were reduced compared with raw material. Moisture content of solid products was also reduced to less than 30% about 3 days after putting in the desiccator filled with dry silica gel.
