Experimental Study of Fe-Mn Minerals as Low-Cost Oxygen Carriers in Chemical Looping Combustion Processes
Authors: , ,
Abstract: The main challenge in the technology of Chemical Looping Combustion (CLC) is to find viable candidate materials for use as oxygen carriers. Low cost, naturally occurring minerals are examined in this work, which can substitute costly manufactured materials with comparable compositions. Two minerals with high content of Fe and Mn oxides are studied experimentally in the CLC process. Both materials exhibit satisfactory performance in terms of Oxygen Transfer Capacity (OTC), activity towards CH4 oxidation, low selectivity to CO and H2, and stability in multiple redox cycles. The materials are physicochemically characterized before and after their use, in order to investigate changes in their physicochemical properties as a result of multiple redox cycles.
