Sucrose, a renewable resource from sugarcane, was reformed to hydrogen using supercritical water as a novel reacting medium that acts both as a solvent and a reactant. Supercritical water has been demonstrated as an effective reformation medium for a variety of hydrocarbons including renewable energy sources derived from methanol, ethanol, and biodiesel. Temperature and space time were held constant while pressure was varied from 17.24 to 31.03 MPa in a 400 mL Hanyes Alloy 230 tubular reactor and the resultant effect on gaseous hydrogen production was investigated. In addition, the water-to-fuel mass ratio was varied from 3 to 18 and the effects on gaseous hydrogen production explored.
