Abstract: | This article is an overview of oxidation of coal in supercritical water. Coal ignition modeling and the newest kinetic studies are introduced. In addition, sulfur and nitrogen transforma- tions during supercritical water oxidation of coal are analyzed. Energy utilization and exergy effi- ciencies of oxidation of coal in supercritical water are also discussed, and series of equations are proposed for the detailed calculation. Finally, the scientific problems need to solve are proposed. |
