して固定し、除去される。Hereinafter, the method and apparatus for decomposing and removing carbon monoxide or carbon dioxide according to the present invention will be described with reference to the drawings. FIG. 1 is a block diagram of a removing device for achieving the present invention. In the figure, this removing device is composed of a substantially T-shaped quartz discharge tube 1. The discharge tube 1 is an inductively coupled plasma (ICP :) which is wound around a pipe into which a gas to be decomposed, in this embodiment, carbon dioxide (CO 2 ) gas is introduced.
A high frequency coil 2 for generating inductively coupled plasma is arranged, and the high frequency coil 2 for generating ICP is connected to a power source 3 for high frequency generation. Further, the discharge tube 1 has a pair of electrodes 5 and 6 arranged in a conduit extending in a direction substantially perpendicular to a conduit into which gas is introduced. A DC voltage is applied by being connected to the decomposition electric field electrode 4. Electrode 5 of the discharge tube 1 to which a positive voltage is applied
The end on the side is communicated with the exhaust pump 10, while the end on the side of the electrode 6 to which a negative voltage is applied is closed. In the apparatus having the above structure, CO 2 gas 7 to be decomposed is introduced into the tube through the inlet 1a of the discharge tube 1 to a pressure of 1 atm, and the high frequency power source 3 supplies the IPC generation high frequency coil 2 to the IPC generation high frequency coil 2, for example. When high frequency power of 27.12 MHz is applied, the CO 2 gas 7 in the discharge tube 1 becomes inductively coupled plasma and decomposes into C atoms and O atoms. At that time, when comparing the decomposed C atom and O atom, the C atom is
Since it is 11.26eV, which is lower than the 13.61eV of O atom, it is easy to become a positive ion, while the electron affinity of O atom is 3.08eV.
Since it is higher than 1.12 eV of C atom, it is likely to become a negative ion. Therefore, under the optimum discharge conditions, most of the CO 2 gas 7 is decomposed and ionized into C + and O − . When an electric field is applied to the decomposed and ionized ions by the electrodes 5 and 6, C +
The ions 9 and the O − ions 8 are attracted and move toward the electrodes having different signs. The mobility of ions at this time depends on the electric field strength determined by the size of the electrodes 5 and 6, the distance between the electrodes, the applied voltage, and the like. Incidentally, in the present embodiment, the diameter t of the discharge tube is
30 mmφ, distance between electrodes 1 is 50-100 mm, applied voltage is 100-
Although not shown in detail in the figure, the electrodes 5 and 6 have a cylindrical shape arranged along a duct, the cylindrical length is 10 mm, the wall thickness is several mm, and the outer The diameter was set to a value substantially equal to the tube diameter t. As a result, it was observed that the ion separation was suitably performed and that CO 2 introduced under normal pressure was ionized at an ionization rate of several% to several tens%. O − ions 8 attracted to the anode 5 side pass through the electrode 5,
It is exhausted by the exhaust pump 10 and released into the atmosphere. On the other hand, C + ions 9 attracted to the cathode 6 side are
After passing through and colliding with the instrument wall and being fixed there,
Recovered and removed. FIG. 2 shows a removing device for realizing another embodiment of the present invention, which is constructed by connecting the devices shown in FIG. 1 above in multiple stages. The same parts are designated by the same reference numerals and the description thereof will be omitted. That is, in this removing device, the second and third removing devices are connected to the ends of the discharge tube 1 where C + ions and O − ions are decomposed and move. The second and third removing devices are
It has the same structure as that shown in FIG. In the removing device configured in this way, the first stage is divided.
The CO 2 gas 7 is further decomposed by the second and third removing devices based on the above-mentioned theory, its ionization rate is improved, and C + ions and O − ions are removed. FIG. 3 shows a removing device according to still another embodiment of the present invention. In this embodiment, the components denoted by reference numerals 1 to 10 have the same function and operation as those of the embodiment shown in FIG. In the device of this embodiment, a carbon ion recovery device 11 is arranged in communication with the end of the discharge tube located on the back side of the cathode 6 of the device shown in FIG. The carbon ion recovery unit 11 is a metal or metal oxide capable of fixing remove the C + ions 9 reacts with C + ions 9 decomposed is configured filled. Examples of the metal that reacts with the C + ion include Fe, Co, N
At least one of i and Mn can be applied. In the removing apparatus configured as described above, the O − ions 8 are exhausted by the exhaust pump 10 and the separated C + ions 9 are discharged.
Is chemically active in the excited state, it is easily bonded and fixed to the metal that reacts with the carbon ions in the carbon ion recovery apparatus 11, and is removed.

できる。As described above, according to the present invention, since the carbon ions and oxygen ions decomposed by the inductively coupled plasma are electrically removed by utilizing the difference in the electrical properties, the decomposition of CO 2 gas and the Carbon ions can be easily recovered, and if oxygen ions are released into the atmosphere, they have an effect on environmental recovery. Further, the above method can be achieved by a device having a relatively simple structure. Further, a binding substance of carbon and a metal is generated, and useful hydrocarbons and the like can be recovered from the binding substance, and thus, other usefulness can be obtained in addition to CO 2 removal measures for preventing the greenhouse effect. Further, the decomposition by the inductively coupled plasma is carried out without performing the decomposition by the combustion device as in the conventional device, so that the device can be miniaturized without the need of the heat source for temperature.
