| Ozone is one of the strong oxidation agents which has much potential for disinfection, deodorization, decolorization and decomposition of organic materials. In this study, a Co-catalyst activated with ozone for removing chemically offensive odors effectively was developed. The characteristics of the catalyst developed and removal efficiencies of odors were also investigated. The Co-catalyst was synthesized by the impregnation method with activated carbon and it was observed by scanning electron microscopy. Benzene and toluene removal experiments were conducted for examining the oxidation capacity of the catalyst in a packed bed reactor. There was a big difference of removal efficiency between ozone only and ozone/catalyst. To observe the adaptability of the developed catalyst, chemically offensive odors such as mercaptans, sulfides and ammonia from food waste were removed with a pilot-scale deodorizing apparatus packed with Co-catalyst. Mercaptans and sulfides had good removal efficiencies over 90% though ammonia showed lower efficiency. |
