HALOGEN-CONTAINING ORGANIC COMPOUND-DECOMPOSING CATALYST, PRODUCTION THEREOF, AND WASTE GAS TREATMENT METHOD

摘要

PROBLEM TO BE SOLVED: To decompose halogen-containing organic compounds at high efficiency for a long duration by preventing deterioration of catalytic activity by deliquescent components. SOLUTION: This halogen-containing organic compound-decomposing catalyst comprises a component having a function of oxidizing and decomposing halogen- containing organic compounds, and a coating formed on the component has a coating containing an organic porous component, a mixture coating containing an organic porous component and an inorganic oxide particle or a mixture coating containing an organic porous component and a catalyst component particle formed thereon. The method for producing the halogen-containing organic compound decomposition catalyst comprises applying at least one type of slurries or emulsions containing components selected from an organic porous component, a mixture containing an organic porous component and an inorganic oxide particle, and a mixture containing an organic porous component and a catalyst component particle to the surface of a halogen-containing organic compound decomposition catalyst and forming a porous coating by drying the resultant halogen-containing organic compound decomposition catalyst.
