Effect of Heating Method on Hydrogen Production by Biomass Gasification in Supercritical Water

Abstract EN

The glucose as a test sample of biomass is gasified in supercritical water with different heating methods driven by renewable solar energy.

The performance comparisons of hydrogen production of glucose gasification are investigated.

The relations between temperature raising speed of reactant fluid, variation of volume fraction, combustion enthalpy, and chemical exergy of H2 of the product gases with reactant solution concentration are presented, respectively.

The results show that the energy quality of product gases with preheating process is higher than that with no preheating unit for hydrogen production.

Hydrogen production quantity and gasification rate of glucose decrease obviously with the increase of concentration of material in no preheating system.
