Abstract: A volatilization vessel, such as a carbon reduction kiln, comprises a processing environment and associated apparatus and an air-input component configured to maintain a negative pressure and an oxygen-rich atmosphere during a time period of elevated temperature, so as to produce a beneficiated coal fly ash having 2% or less LOI from landfilled or ponded waste coal fly ash. The waste coal fly ash is preferably exposed to indirect heat when received in such zones. The system may include a carbon capture system operatively connected to the carbon reduction kiln.

Abstract: A system for beneficiating landfilled or ponded waste coal fly ash makes use of a carbon reduction kiln comprising multiple independent heat zones so that the waste coal fly ash is preferably exposed to indirect heat when received in such zones. The system may include a carbon capture system operatively connected to the carbon reduction kiln.
