Abstract

A redox catalyst with MoO₃ loaded on CaMnO₃ perovskite was evaluated for chemical-looping oxidative dehydrogenation (ODH) of propane to produce propylene. This approach requires less energy for the production per unit of propylene with minimum CO₂ emission, which is highly desirable from an environmental perspective. H₂-TPR indicates that the incorporation of MoO₃ minimizes the release of surface oxygen, which is favorable for high propylene selectivity. XRD reveals the presence of active sites, while scanning SEM-EDX show uniform dispersion of deposited MoO₃ on CaMnO_3. XPS analysis demonstrates that MoO₃ addition promotes the formation of lattice oxygen which improves the propylene selectivity. The highest propylene yield of 30.6% with a propylene selectivity of 59% was achieved at 550 ℃ with 10% MoO₃/CaMnO₃. The catalysts also show stable activity in successive redox cycles. The addition of MoO₃ enhances propylene yield and selectivity, due to free lattice oxygen, as revealed by XPS and H₂-TPR.
