This report presents an assessment of the potential of chemical looping in the context of a Fischer-Tropsch (F-T) coal-to-liquids (CTL) plant. This analysis-of-concept report was intended to confirm that the thermo chemical operations were in heat balance at temperatures compatible with an operable system. The analysis also included simulations of an entire coal to F-T liquids process, including the proposed looping scheme. The specific method tested in this report is a chemical looping concept that uses iron oxide (Fe2O3) to react with the unreacted synthesis gas (H2 and CO) and light hydrocarbons in the effluent tail gas from an F-T reactor.
