For example, the activated carbon obtained in JP-A-1-127812 according to the invention of the present inventors can be used. Further, a waste tire containing a metal wire is heated to 400 to 900 ° C, preferably 700 to 800 ° C.
Activated carbon obtained by burning in the presence of oxygen and in the presence of CO 2 and water vapor, wherein the activated carbon has a cross-linked lattice which is hardly graphitized in the gaps between the carbon microcrystals, and has a pencil hardness of B -6B, a pore size of 100-400 Å, a specific surface area of 150-500m 2 / g, and the pore volume is 1.3-5.0ml / g, carbon microcrystals and non-graphitizable irregular arrangement Those consisting of carbon can also be used.

Preferably, the CEC (base substitution capacity) is 8-1.
3, preferably 9-12. In addition, as said metal wire, there exist a steel wire, a silicon steel wire, etc., for example. The air for burning the waste tire preferably has a high humidity, for example, a relative temperature of at least 60%. If necessary, water is added to the combustion atmosphere by an appropriate means. After activated carbon production,
The metal wire fragments are removed, for example, using a magnet, and then the obtained activated carbon particles 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. This method is a method of producing activated carbon by igniting a carbon-containing material in the absence of conventional air (oxygen) and then adding active hydrogen, or sufficiently carbonizing a carbonaceous material, and then obtaining the carbonized material. This is completely different from the method of producing activated carbon in which carbon is treated with steam or chemicals.

The invention is bound by any particular theory,
While not wishing to be limited, it seems that this mechanism can be considered 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, act catalytically or physically on the material, and furthermore, CO 2 present in the combustion atmosphere.
