| Abstract: | Hydrogen can be obtained from organic compounds by Supercritical Water Gasification (SCWG). In this paper, the influence factors, intermediates and reaction pathway of glucose, methanol, cellulose, lignin, real biomass and organic waste/wastewater by SCWG are summarized. The effect of catalyst such as alkali metals, ZrO2, activated carbon, noble and transition metal on gasification efficiency and gasification mechanism is illustrated and which is suggested that the study of heterogeneous catalytic reaction is very important for the development of SCWG. The thermodynamics of SCWG is analysed, the difficulty for scale-up of SCWG is discussed and three pilot-scale SCWG units in the world are introduced. The research trends in SCWG are proposed. |
