PURPOSE:To provide granulated activated carbon properly controllable in its mechanical strength without significantly lowering the adsorbency of the activated carbon. CONSTITUTION:The objective granulated activated carbon activated by heating, composed of (A) powdery carbon, (B) solid powder, and (C) a binder. The component A, said powdery carbon 1, is <=150mum in particle diameter; and the component B, said solid powder 2, which is thermally and chemically more stable than the powdered carbon, is <=10mum in mean particle diameter which is 1/5 to 1/20 times that of the powdery carbon (e.g. a metal such as Al or Fe, metal oxide such as alumina or iron oxide, silica, ceramic). |
