Abstract

The present disclosure is directed to an activated carbon-based sorbent composition for the sequestration of contaminants from a medium, methods for sequestering the contaminants from the medium, and a method for the manufacture of an activated carbon-based sorbent composition. The activated carbon of the sorbent composition may be derived from low ranking coal, such as sub-bituminous coal, lignite coal, PRB coal), non-coking coal or "soft" starting materials such as cellulosic material, such as wood fiber, peat, soft nutshells. The activated carbon-based sorbent composition includes one or more binding agents to increase the mechanical hardness of the composition. The method comprises reagglomerating a carbon-comprising feedstock with the one or more binding agents before activating the composition to form the activated carbon-based sorbent composition useful for the sequestration of contaminants from a medium.
