Activated carbon and process for producing the same

An activated carbon comprising an activated carbon particle and titanium dioxide fine particles having an average particle size of not more than 10 .mu.m present at least on the surface thereof, which activated carbon contains substantially no carbon precursor on the surface thereof and has the lightness value L thereof of not more than 30.

A process for producing activated carbon carrying titanium dioxide having an average particle size of not more than 10 .mu.m at least on the surface thereof and having a lightness value L of not more than 30, with process comprises the steps of pulverizing coal, granulating the pulverized coal, carbonizing and activating the granules, wherein titanium dioxide is added to the coal before activation thereof.

A process for producing activated carbon carrying titanium dioxide having an average particle size of not more than 10 .mu.m at least on the surface thereof and having a lightness value L of not more than 30, which process comprises the steps of finely pulverizing the carbonaceous material, mixing with a binder, granulating the resultant mixture, carbonizing the granules and then activating carbonized substance, wherein titanium dioxide is added to the starting carbonaceous material before activation.
