O₂ハイドレート連続生成技術の開発と環境浄化分野への適用

抄録

Ozone（O₃）is a strong oxidant and harmless for environment because of its nature of decomposing to oxygen. Owing to these advantages, there are many applications of ozone in industry, for example purification of water, sterilization of perishables. However, because of decomposing reaction, O₃ is difficult to preserve. Expand the industrial use of ozone, preservation technology of ozone needs to be developed. O₃ clathrate hydrate（hydrate）can preserve O₃ molecules in each cage composed of water molecules. Therefore interaction between O₃ molecules is prevented and decomposition of O₃ can be prevented. In this study, we designed the system for continuously forming O₃ containing hydrate. Long-term preservation for 6 months of the produced sample is possible at 213 K with 50% O₃ in hydrate remaining. At the high temperature side, it is possible at 263 K and 268 K for 6 hours without decreasing the O₃ concentration. Furthermore, we examined decomposition effect of a malodorous component using O₃ gas from O₃ containing hydrate.
