【Abstract】 The continual growth in transportation fuels and more strict environmental legislations have led to immense interest in developing green biomass energy.In this work,a proposed catalytic transformation of oxygenated organic compounds（related to bio-oil） into pure hydrogen was desighed,involving the catalytic reforming of oxygenated organic compounds to hydrogenrich mixture gas followed by the conversion of CO to CO₂ via the water gas reaction and the removal of CO₂.The optimization of the different reforming catalyst,the reaction conditions as well as various sources of oxygenated organic compounds were investigated in detail.The production of pure hydrogen,with the H₂ content up to 99.96%and the conversion of 97.1%,was achieved by the integrated catalytic transformation.The reaction pathways were addressed based on the investigation of decomposition,catalytic reforming,and the water gas reaction.更多还原
