Book excerpt: Development of a model that can be used to predict oxidation rates of copper to cuprous and cupric oxide (Cu2O and CuO, respectively) in the air reactor of a Chemical Looping Combustion (CLC) system is the primary focus of this thesis. The proposed oxidation model, which is based in Wagner Theory and defect chemistry, describes the fundamental processes occurring during copper oxidation. Consequently, it provides better predictive capabilities over a wide range of temperatures and pressures, as well as characteristic particle geometries (spheres, cylinders and plates) than the phenomenological models that are currently being used to predict oxidation rates of copper-based oxygen carriers used in CLC systems. In addition to developing this oxidation model, cuprous and cupric oxide reduction experiments with gaseous fuels like carbon monoxide, hydrogen and methane, and solid fuels like char, wyodak coal, and corn stover, were performed to characterize reaction rates in the fuel reactor of CLC systems. Oxidation rates obtained from the oxidation model, and measured rates from the reduction experiments were used to estimate the size and oxygen carrier loading for a 10 MWth CLC system.
