To provide a conversion treatment process for converting a material to be treated which contains an organohalogen compound(s), into nontoxic inorganic compounds at a high efficiency.
This conversion treatment process for subjecting a halogen(s) in an organohalogen compound(s) and a halogen-free organic compound(s) in a residual gas to conversion treatment into nontoxic inorganic matter comprises: gasifying or atomizing a material to be treated which contains an organohalogen compound(s), or an organohalogen compound(s) and an organic compound(s); subjecting the gasified or atomized material to catalytic reaction with particles of calcium oxide, barium oxide or a mixture of them, which particles are heated to 400-700°C, while coutercurrently and continuously moving the particles, to convert a halogen(s) in the organohalogen compound(s) into a calcium and/or barium halide(s); and bringing the residual gas remaining after the catalytic reaction into contact with a platinum or palladium catalyst deposited on a ceramic carrier, at 200-500°C to subject the residual halogen-free organic compound(s) to combustion treatment.
