ABSTRACT:
An apparatus and process for preparing activated carbon from a wood or wood residue feedstock using fluidized bed technology. The fluidized bed apparatus has a number of wood residue inlets that allow differing residence times in the fluidized bed apparatus appropriate for the wood or wood residue feedstock to be carbonized. The carbonized material may then be activated to form activated carbon.
