摘要
对煤的超临界水氧化(Supercritical Water Oxidation,SCWO)技术进行综述,介绍了煤颗粒在超临界水中的点火模型和最新的反应动力学研究,分析了煤中硫、氮等元素变迁路径。从理论层面讨论了煤的SCWO过程能量的利用方法,归纳了SCWO过程中反应系统、单个组件效率计算方程。最后,提出了尚需解决的科学问题。
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.
