Hydrogen formation from glucose was examined using a batch reactor in high temperature high pressure water at 300°C. Homogenous catalysts (H 2SO4 and NaOH) were not effective for H2 formation from glucose at this condition. Heterogeneous catalysts: Ag 20, CuO, Cr2O3, Fe2O3, MgO, MnO2, MoO3, NiO, rutile TiO2, and ZnO, were applied and then it was found that MnO2 and ZnO effectively promoted H2 formation. In order to enhance H2 yield, glucose in high pressure high temperature water was partially oxidized in the presence of ZnO. As a result, 25 % H2 (glucose mole basis) was obtained. In this reaction, by-production of methane was not observed, The enhancement of H2 yield was not observed when ZnO was located at gas phase. It suggested that a precursor of H2 formed in the aqueous phase.
