Abstract
Methods and systems for producing activated carbon from a particulate coal feedstock that include the introduction of a buffering gas, a moisture spray, a finest carbon fraction as a fuel, and certain gas ratios. Different methods and system configurations allow the production of activated carbon or other heat-treated carbons while concurrently avoiding adverse reaction conditions.
