Abstract:
1. An apparatus for decomposing fluorine compounds which contain at least one of PFC, HFC, SF 6 and NF 3 , said apparatus comprising a single reactor having means therein for holding a fluorine compound decomposition catalyst for decomposing said fluorine compounds charged into said reactor in an upstream portion thereof and means therein for holding a harmful compound removing catalyst having a reaction temperature of 650-850° C. for the decomposition of at least one of SO 2 F 2 and N 2 O, formed by said decomposition, charged into said reactor at a portion downstream of where said decomposition catalyst is charged into said reactor whereby said catalysts are contained in said reactor in pile form; a single heater for heating said catalysts in said reactor; a moisture supplying unit for adding moisture to said fluorine compound supplied to said reactor; an inert gas supplying unit for adding an inert gas as a dilutent gas; and an oxygen supplying unit for adding oxygen or an oxygen-containing gas to a gas containing at least one of SO 2 F 2 and N 2 O formed by decomposition of said fluorine compounds.
