Design Aspects and Insights From Experimental Data in Chemical Looping with Oxygen Uncoupling for Solid Fuel Combustion

Chemical Looping with Oxygen Uncoupling is a potential combustion method being researched for solid fuels, which would assist in the economic capture of carbon dioxide. An order of magnitude process engineering analysis has been developed based on existing literature and insights from in-house kinetic experiments conducted on copper oxide as an oxygen carrier. In this study, data from in-house kinetic experiments has been employed to establish criteria for appropriate temperature and residence time for the air and fuel reactor. The importance of an optimum recirculation of metal in the Chemical Looping with Oxygen Uncoupling system will also be discussed. The talk would also highlight on the utilization of global coal char oxidation kinetic studies from literature in conjunction with the time required for oxygen release by cupric oxide, for investigating the residence time requirements in the fuel reactor.
