抄録

For supercritical water gasification of biomass, it is said that biomass components such as cellulose is first dissolved into hot compressed water, and then decomposition reaction including hydrolysis and gasification takes place. If it is the case, particle size should not affect the gasification characteristics because no solid particle should be remaining in the supercritical water reactor. However, this hypothesis has not been systematically investigated. In this study, biomass of the same kind but with different particle diameter was gasified in supercritical water, and surprisingly, effect of particle size was observed.
