Abstract
Methods and systems for producing activated carbon from a particulate coal feedstock that involve one or more of 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.
Claims8
A method for producing activated carbon in a heat treatment system that conveys particulate carbon feedstock to a reactor containing a burner flame comprising, injecting moisture through a center portion of the burner flame down the linear length of the reactor through one or more spray lances such that said carbon feedstock is not contacted by said moisture until said feedstock undergoes at least one revolution or travels at least one half reactor diameter within said reactor.
