（実施例） 以五、この発明の一実施例を図面に基づいて説明する。(Example) Hereinafter, one embodiment of the present invention will be described based on the drawings.
まず、その構成について説明すると１反応室１は中空状
に形成しており、加熱手段２（実施例では、電気炉であ
るが、これに限定されない）で約り００℃〜約４００℃
（好ましくは約３００℃）に維持可能に構成している。First, to explain the structure, 1 reaction chamber 1 is formed in a hollow shape, and heated by heating means 2 (in the example, an electric furnace, but not limited to this) to a temperature of about 00°C to about 400°C.
(preferably about 300°C).
なお、該実施例では、反応室１は長さを約５０ｍｍ、外
径を約２０ｎｍの管を用いた。３は粒状のマグネタイト
（Ｆａ、Ｏ，）である。In this example, the reaction chamber 1 used was a tube having a length of about 50 mm and an outer diameter of about 20 nm. 3 is granular magnetite (Fa, O,).
つぎに、その作用について説明すると、まず。Next, let me explain its effect.

２／３Ｆ’ｅ、０４＋１／６ ０．−ｍ−→γＦ ｅ
７０゜となる。The reaction chamber 1 is filled with magnetite 3. Then, the room temperature of the reaction chamber 1 is brought to about 300'C by the heating means 2, and then exhaust gas containing oxygen is supplied from the inlet of the reaction chamber 10. Then, the oxygen comes into contact with the magnetite 3 and reacts, and the magnetite turns into maghemite. The reaction is: 2/3F'e, 04+1/6 0. −m−→γF e
It becomes 70°.
実験によると、ガス流斌６０〜７０１１１／＋ｍｉで１

た。According to experiments, 1 at gas flow rate 60~70111/+mi
When the oxygen was supplied for 0 minutes, the amount of oxygen was approximately 6.2% per volume, but it was significantly reduced to approximately 0.59% at the outlet.
したがって、排ガス対策を必要とする、例えばディーゼ
