BaCoO3-δ perovskite-type oxygen carrier for chemical looping air Separation, part Ⅱ: Design of the monolithic oxygen carriers

•Monolithic oxygen carriers were prepared by loading BaCoO3-δ powder perovskite onto cordierite ceramics for CLAS.•The oxygen release performance of the monolithic oxygen carriers was simulated using CFD numerical method.•The monolithic oxygen carrier primarily released O2 via the lattice oxygen of BaCoO3-δ perovskite.•The square was a more suitable cross-section shape for the loaded material.
