Supercritical water processing technologies for environment energy and nanomaterial applications This book systematically presents the technical aspects of supercritical water oxidation and supercritical water gasification for energy and environmental applications which include reactor design construction materials corrosion salt precipitation etc. The book provides a comprehensive introduction to the properties of supercritical water and the industrial applications reaction mechanisms and reaction kinetics of supercritical water oxidation (SCWO) and supercritical water gasification (SCWG). The reactions occurring in supercritical water are complex and studying their reaction mechanisms is of great importance for the development of supercritical water processing technologies. Accordingly the book explains the oxidative mechanisms and kinetics of organic matter in supercritical water in detail. However the harsh reaction conditions in supercritical water can easily create severe reactor corrosion and salt deposition problems. Therefore the book also comprehensively reports on the mechanism analysis state of research and development trends regarding these two problems. Lastly the book summarizes the development of supercritical water processing technologies including studies on SCWO and SCWG as well as near zero emission systems of pollutants based on SCWO technology. In short the book provides a wealth of valuable information for all readers who are interested in using SCWO for organic waste treatment and in using SCWG for hydrogen production with wet biomass
