れる。FIG. 1 shows an electron micrograph of the activated carbon of the present invention. The magnification is 1000 times. This indicates a large pore size, large pore volume and irregular arrangement. The following table compares the activated carbon of the present invention with commercially available activated carbon. As is clear from the above table, the activated carbon of the present invention has a lower hardness, a larger pore diameter, and a larger pore volume than commercially available activated carbon. Then, large particles and molecules can be adsorbed. In view of the electron microscopic structure, the activated carbon of the present invention has a small specific surface area, so it seems that the activated carbon cannot be deodorized or decolorized. However, surprisingly, it exhibits excellent deodorizing and decolorizing effects. This is likely due to the large pore size and large pore volume.

Waste tires containing metal wire 400 to 900 ° C., preferably, 700 to 800 ° C., in the presence of oxygen, and CO 2
And by burning in the presence of steam. Examples of the metal wire include a steel wire and a silicon steel wire.

異なるものである。After the activated carbon is produced, metal wire fragments are removed, for example, using a magnet, and then the activated carbon particles obtained are sieved to obtain particles having a desired particle size range. Therefore, according to this method, a desired particle size can be obtained without forming the activated carbon into a pyret. Of course, if necessary, pellets smaller than the desired particle size may be pelletized to obtain the desired particle size. In this method, carbon-containing materials are ignited and carbonized in the absence of conventional air (oxygen),
This is completely different from a method for producing activated carbon by adding active hydrogen or a method for sufficiently carbonizing a carbonaceous material and then treating the obtained carbon with steam or a chemical.

The present invention is based on any particular theory,
While not wishing to be bound or restricted, it seems that this mechanism can be thought of as follows. That is, during combustion, the metal wire (thin metal stranded wire) is broken and broken into pieces, which are scattered in the waste tire material, catalytically or physically act on the material, and furthermore, CO 2 present in the combustion atmosphere.
