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.

Method of decomposing halogenated hydrocarbon gas

A method for blowing synthetic resins as a fuel into a furnace comprising: processing synthetic resins consisting essentially of film shaped synthetic resins by melting or semi-melting the synthetic resins by heat to produce granular synthetic resins having a bulk density of at least 0.3 and angle of repose of up to 40 degrees; pneumatically feeding the granular synthetic resins from the processing; and blowing the pneumatically fed granular synthetic resins into a furnace.

Method for blowing synthetic resins as a fuel into a furnace

A method for processing synthetic resins into a furnace fuel, comprising melting or semi-melting synthetic resins consisting essentially of film shaped synthetic resins to produce granular synthetic resins having a bulk density of at least 0.3 and an angle of repose of up to 40 degrees, wherein the angle of repose is a base angle when the granular synthetic resins are dropped on a horizontal plane surface.

Catalyst and method for producing phenols

A process for decomposing ammonia recovered from coke oven gas through catalytic oxidation in the presence of oxygen gas, which comprises contacting a catalyst containing at least copper oxide or vanadium oxide in a fluidized state with the ammonia vapor. In the process of the invention, the reaction can be conducted at a low temperature of 400.degree. to 600.degree. C. and the generation of NO.sub.x is very small in quantity.

Catalytic oxidation of ammonia

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.
