PROBLEM TO BE SOLVED : To provide a processing agent for halogenated gases that can decompose compounds containing halogens such as PFCs, HFCs, HCFCs and CFCs efficiently at a comparatively low temperature, make harmful substances formed by decomposition harmless and continuously process the halogenated compound regardless of its concentration in a gas for a long time by being combined with an apparatus for harmless disposal. SOLUTION : The processing agent for halogenated gases contains at least one compound selected from the group consisting of a chloride of an alkaline metal, a chloride of an alkaline-earth metal and a fluoride of an alkaline metal and is composed of calcium oxide or magnesium oxide prepared by baking under a nitrogen atmosphere.
