抄録

Chemical looping is one of the ideal processes for generating power and capturing CO₂ simultaneously without requiring additional energy. In this process, oxygen carriers are used for combusting solid fuels, and their activity should be improved to enhance energy efficiency in the process. In this study, we focus on the effect of K addition on the chemical looping reactivity of ilmenite (IL) used as an oxygen carrier. Scanning electron microscopy and X-ray diffraction measurements were performed to evaluate the K dispersion in K-added IL and the structural changes in IL by the K addition.
