| 제목 | A Chemical Agent Simulant Oxidation Kinetics in Supercritical Water |
| 초록 | Supercritical Water Oxidation (SCWO) has been proved to be a powerful technology to eleminate a wide range of wastes, but there are few references in the literature about the application of SCWO to chemical weapon agents wastes. In this work, SCWO have been tested to treat chemical agent simulant Dimethyl methylphosphonate (DMMP), which is similar to the nerve agent VX and GB (Sarin) in structure. All experiments were performed in an isothermal tubular reactor with a H2O2 oxidant, at temperature from 300 to 405 oC, and pressure 240 bar. The total organic carbon concentration of DMMP in feed tank were between 1800 and 10000 ppm. The initial concentration of H2O2 were between 1.4 and 4.4 M, which were the stoichiometric amount needed to oxidize DMMP completely to carbon dioxide. It is found that the oxidative decomposition of DMMP proceeded rapidly and a high TOC decomposition up to 90% was obtained within 7 second at 400 oC. As the result of experiment, the power-law rate expression that best correlates the experimental results for the conversion of TOC was determined to be: rate = -1.2 x 102 exp(-46.5071/RT)[TOC]0.96[H2O2]0.27 |
