Abstract
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.
