    摘要: A method and an apparatus for decomposing halogenated hydrocarbon gas economically and stably without relying on any special treatment and without generating dioxins. A catalyst to decompose halogenated hydrocarbon gas, 4, is supported on a carrier 3. A target gas, which contains the halogenated hydrocarbon gas, is passed through the carrier 3, while heating the carrier 3 using an electromagnetic induction heating mechanism 5, 6.

    摘要: For carrying out a process for decomposing, into hydrogen and nitrogen, ammonia recovered from a coke oven gas by combining a catalytic combustion of ammonia and a catalytic decomposition of ammonia utilizing a waste heat by said combustion, a basic compound as a required catalyzer is added to ruthenium supported on alumina, or ruthenium as a required catalyzer is supported on a basic compound, whereby ammonia may be decomposed effectively at ranges of low temperatures as not more than 500.degree. C.
