Abstract
Chemical-looping process is a prospective energy conversion system with cost-effective CO_2 separation and efficient H_2 production. To accomplish this process and make this process more efficient, oxygen carrier with high-speed oxygen exchange has to be invented. Specifically, to achieve high-efficiency H_2 production, the reaction rate and the reaction ratio of oxidation of the oxygen carrier are significant. Therefore, the reaction rate and the reaction ratio of redox reactions of various oxygen carriers were investigated, and the reaction ratio of oxidation under the condition with various temperatures and partial pressure of H_2/H_2O was also investigated.
