Abstract
A body made of carbon particles bonded together with bentonite clay and cellulose fibers, wherein in weight percent based on carbon, the bentonite content is about 4% to 20%, and the cellulose fiber content is about 2% to 10%. A method of making the body which involves forming an aqueous mixture having a composition in weight percent based on carbon of about 5% to 8% organic binder which can be cellulose ethers, cellulose ether derivatives, and combinations of these, about 4% to 20% bentonite clay, about 2% to 10% cellulose fibers, and the balance being activated carbon particles, forming the mixture into a body, and drying the body.
