Dry processing methods fluorine selective separating agent and the fluorine-containing compound for dry treatment

PROBLEM TO BE SOLVED: To provide a method for treating a fluorine selective separation agent and a fluorine-containing compound capable of absorbing in dry condition halogen dissociated from a vaporized halogen-containing compound in a processing agent on site and more selectively increasing a fixed amount of fluorine than in a conventional art so as to selectively separate fluorine from a fluorine-containing compound under dry and low-temperature conditions of less than 800°C. SOLUTION: The gaseous fluorine-containing compound reacts with a fluorine selective separation agent in an environment that is controlled at a temperature of 600°C, and the fluorine in the fluoride is fixed to a catalyst of the fluorine selective separation agent and a solid alkali agent. The fluorine selective separation agent is made by coating an oxide system catalyst exhibiting solid acid coated on the solid alkali agent. This allows the halogen dissociated from the vaporized halogen-containing compound to be catalytically absorbed to the reaction processing agent on site in dry condition, thereby enabling the system to more selectively increase the fixed amount of fluorine than in the conventional art.
