Hydrogen production from gasification in supercritical water (SCW)
In this process, biomass is treated in supercritical water to be converted into fuel gases, which are rich in hydrogen. Water plays various roles in facilitating the gasification reaction, due to its unique ability and properties. The properties of water displayed beyond critical point plays significant role for chemical reactions. The hot compressed water molecules can participate in various elementary reaction steps as reactant, catalyst as well as medium. The overall reaction can be written as [
