Chemical loop is a process in which the feedstock is converted into electricity and recovered with high added value products accompanying CO2. Efficiency and design of process is dependent on the performance of the components, including the participation oxygen carrier in the conversion of various redox. Here we examined the activation of iron oxide supported on zirconia for hydrogen production, in terms of morphological changes, and discuss its reactivity. Activation of fresh particles primarily was due to the enhanced gas / ionic oxygen diffusion on a support material. Here, the two main factors, lower oxides - iron oxide support interacts with localized stress in hematite interface, that there was a fundamental reason for activation of the particles was found. We also, consider the optimal authentication method. Conventional redox cycle particles without having to steam oxidation as a repeating cycle, slowly activated while the particles are rapidly activated with air. To enable rapid fresh particles, without having to steam oxidation, a plurality of redox cycles are recommended |
