ABSTRACT:
A body made of activated carbon particles bonded together with a clay binder which can be attapulgite and/or sepiolite, and a plasticizing organic binder. The organic binder is more typically cellulose ether and/or cellulose ether derivative at a level of about 2 to 12 wt. % and the clay about 2% to about 30 wt % based on the carbon and clay. A method for making the body involves forming an aqueous mixture composed of the clay, organic binder and carbon, forming the mixture into a body, and drying the formed body.
