Supercritical water gasification is expected to be the next-generation wet biomass conversion technology. In Chugoku District, this technology has been studied in the framework of Chugoku District Supercritical Water Gasification Research Group, and 1 t/d pilot plant has been built and operated. During the development the importance of rapid heating has been determined, and addition of radical scavenger has been proposed. The development of this technology is reviewed in this presentation.
