摘要

采用间歇式超临界水氧化实验装置

研究了RDX在超临界水中的氧化降解特性

采用色谱-质谱(GC-MS)方法测得RDX降解的主要中间产物

在对中间产物进行分析的基础上

探讨了RDX在超临界水中的氧化降解机理.结果表明

超临界水氧化技术能有效降解RDX

反应温度和反应时间是影响RDX降解效果的主要因素

在反应温度为550℃、压力24 MPa、反应时间150 s的条件下

RDX的降解率可以达到99%以上.RDX降解的主要中间产物为直链烷烃和环状化合物.

Abstract

The supercritical water oxidation(SCWO) experimental facility was used to investigate the degradation characteristic of RDX in supercritical water.The degradation intermediate products were analyzed by using gas chromatograph coupled with a mass spectrophotometer(GC-MS).Based on the analysis on the intermediate products

the degradation mechanism of RDX in supercritical water was researched.The results showed that SCWO technology may degrade RDX effectively.Temperature and reaction time served as the main influence factors in RDX degradation efficiency.A degradation efficiency of RDX may reach 99% under the conditions of 550 ℃

24 MPa and 150 s.The main intermediate products of RDX degradation are linear paraffin and ring compounds by GC/MS measuring.
