A new method to prepare functionalized and impregnated activated carbon from coal is described in this paper.  Ferric chloride and a PRB coal were used as precursors to demonstrate simultaneous coal activation, chlorine functionalization, and iron/iron oxides impregnation in the resulting porous carbon product.  FeCl3 content of the precursor mixture, method used (dry or wet) to prepare the precursor (dry mixing or liquid impregnation), and activation atmosphere and temperature impacted surface area and porosity development  as well as Cl functionalization and iron species impregnation and dispersion in the carbon products.  FeCl3 served as an activation agent, but at a high concentration iron species caused pore plugging in the carbon product.
