摘要：
Chemical looping combustion (CLC) is a kind of efficient combustion technology to capture CO2. In this paper, the reaction characteristics of CO and sintering ore used as an oxygen carrier (OC) in CLC were investigated through thermogravimetric experiments. The effects of the reaction temperature, particle size, and CO concentration on reduction conversions of sintering ore were experimentally studied. The experimental data with high final conversions, obtained during the temperature range of 900 degrees C, were chosen to analyze the reaction kinetics with diverse models and to have an insight of reduction reaction parameters of sintering ore. In addition, the economy of the circulation of sintering ore was theoretically discussed. The tests of 30 redox cycles were conducted at 900 degrees C to investigate the recyclability of sintering ore. The sintering ore samples during the cycling tests were morphologically characterized for better understanding of the reaction mechanism.
