超临界水的应用及其环境中材料腐蚀的研究

Study on Application of Supercritical Water and Relevant Materials Corrosion

介绍了超临界水特殊的物理、化学性质及其目前在化工、环境领域的应用状况,超临界水氧化法是一种很有前途的废物处理技术,在宇航、潜艇、环保等领域具有广泛的应用前景,但高温高压下设备的腐蚀是限制该技术推广应用的主要因素之一。在介绍超临界水的性质及其主要应用的基础上,简述了国内外超临界水中材料腐蚀的研究现状,为新型超临界水反应器的研究与开发提供一定的参考。

The special physical, chemical properties of supercritical water （SCW） and its application in the fields of chemical industry and environment were introduced. Supercritical water oxidation is a very promising method for waste disposal. It has widely application foreground in space navigation, nuke and environment protection et al. fields. However the equipment corrosion under high temperature and pressure is one of the chief factors which limits the technology application of SCW. The research state of material corrosion in SCW was described on base of the properties and application of SCW introduction, which provides some reference for SCW reactor study and development.
