Abstract
Methods and systems for producing activated carbon from a particulate coal feedstock that include the introduction of an activation medium such that the water content of the coal feedstock is equal to or greater than that of the feedstock's naturally occurring state. Different methods and system configurations allow the production of activated carbon or other heat-treated carbons while concurrently avoiding adverse reaction conditions.
