Abstract

An improved method of manufacturing hard activated carbon pellets is disclosed in which a lignocellulose material is chemically activated to form a char and heated to a temperature above about 360.degree. C. which char is ground and then agglomerated in a pin mixer followed by pelleting the agglomerated acid char in the presence of an activatable binder. The pelleted hard activated carbon is then subjected to a final heat activation to yield a product with high density and activity.
