Recently biomass energy is attracting attention, but utilization method for wet biomass can be still developed. Supercritical water gasification is effective to convert wet biomass slurry feedstock into the energy because of water with high reactivity. When such slurry feedstock is used for this gasification, slurry feeder is needed. However, there is no solid procedure for feeding slurry and mass balance in many researches are not well closed. That is why this research is focusing on establishing slurry feeder and making sure key parameters of mixing slurry materials. High pressure container was made for this research and the evaluation of this feeder was conducted by the recovery rate with changing the agitation rate, the amount of feedstock and the distance between the plate and the feedstock. In this research, shochu residue and activated carbon was used as slurry feedstock.
