Abstract
Supercritical water gasification (SCWG) is considered to be one of the potential reforming approaches for hydrogen production as a clean and renewable energy carrier. Various feedstocks-renewable and nonrenewable-can be effectively reformed in supercritical water. This chapter reviews the current status and prospective of the SCWG of liquid-type feedstocks such as methanol, ethanol, glycerol, petroleum-based hydrocarbons, and model biomass compounds such as glucose and lignin. To gain better understanding on the thermodynamic and the hydrogen production mechanism in supercritical water, the hydrogen gas yield of each feedstock reformed under different conditions are compared with the theoretical equilibrium yield calculated by the Gibbs free energy minimization. This review attempts to present the potential, some challenges, and research outlooks of the SCWG of liquid-type feedstocks.
