Summary:PROBLEM TO BE SOLVED: To improve the removability of harmful materials by an activated carbon, by adding titanium dioxide into raw coal before the granulation. SOLUTION: This granulated activated carbon is produced by pulverizing the raw coal, kneading it with a binder, granulating, hardening and carbonizing and activating them. In such a case, titanium dioxide is added into the raw coal before the granulation. As the titanium dioxide, both of the rutile type and the anatase type can be used, and the amount of the titanium dioxide to be added is preferably <=40wt.%, and more preferably <=30wt.% per the pulverized coal.
