ABSTRACT:
An improved process and apparatus for the production and reactivation of activated carbon comprising the passing of a substrate through one or more zones defined by electrodes. Electrical energy passing through the bed of substrate creates heat that supports the devolatilization and activation of the substrate. Steam, carbon dioxide, or an alternative gas can be used to support the activation process, while other zones can be filled with inert gas such as nitrogen to promote pyrolysis reactions. Preferably, these gases pass through the bed in a co-current downward flow with the carbon to prevent fluidization and arcing within the bed.
