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.
Claims3
A process for the production of activated carbon from a carbonized feedstock, comprising the steps of:
- providing a fluidized bed reactor;
- adding particulate material to the fluidized bed reactor to form a bed of particulate material in said fluidized bed reactor;
- adding carbonized feedstock to the fluidized bed reactor;
- further fluidizing the fluidized bed reactor;
- and
- adding superheated steam to the fluidized bed reactor to activate the carbon in the carbonized feedstock
- to produce activated carbon.
