Abstract
This paper summarizes the current status and the international activities in the technologies to decompose fleon (CFC) which can cause ozone depletion in the stratosphere and global warming. Discussions have been given in Japan on combustion decomposing method as a fleon decomposing technology, which can use generally available incinerators. A plasma decomposition process uses a high-frequency plasma device with an input of 182 kW which can process CFC-12 of 48 kg/h at a decomposition efficiency of 99.99% or higher. A reported catalyst decomposition method uses zeolites, alumina, TiO2-ZrO2-based oxide mixture, and iron oxide carrying activated carbon as catalysts. A super critical water decomposition process is reported capable of decomposing almost completely CFC-11 and CFC-113 at 400[degree]C and 320 or higher atmospheric pressure. The United Nations Environment Programme arranges international cooperations on the stratospheric ozone/fleon problem, and the committee has established an ozone depleting substance (ODS) decomposing technology authorization act. The currently available capacities of decomposing devices are by far lower than the banked ODS amount to be provided to decomposition. 3 refs., 3 figs., 7 tabs.
