摘要：
Power generation using chemical looping combustion (CLC) technology has emerged as a promising CO2-capture-based alternative to conventional technology. In this study, the performance of a Ca0.9Mn0.5Ti0.5O3-delta perovskite-type oxygen carrier material for use in fixed-bed CLC reactors is investigated. The main focus of the study is on the material's oxygen-carrying capacity and reactivity with and conversion of syngas in the fixed-bed reactor. Pressurized thermogravimetric analysis in model gases indicates neither Boudouard coking nor reactivity of the oxygen-carrier material toward CO2. A fuel gas conversion of 95% was achieved in the fixed-bed reactor using this oxygen-carrier material.
