LaMnO3 and LaMnO3@mSiO2 oxygen carriers were studied in a fluidized bed reactor for CLC. Their reduction behavior was simulated using classical kinetic models and designated diffusion model, derived by assuming oxygen ion diffusion as the rate limiting step. The higher value of  for LaMnO3@mSiO2 reflects increased difficulty of perovskite reduction.
