제목 Comparison of the performance of chemical looping combustion process using Fe-Mn low-cost particles
초록 In Chemical Looping combustion, a redox reaction occurs in two separate reactors. As a result, CO2 can be separated from the process without any additional CO2 capture facility, and NOx generated during the high temperature combustion process is blocked, and combustion efficiency is also high. In this study, Fe-Mn-based particles using Al2O3 as a support were used for the experiment. In the case of Fe, Fe2+ is not effective in the reaction with methane, but Fe3+ is very effective for oxygen transfer. Therefore, the precursor was composed of Me3+ containing oxides, and the spinel structure, which is structurally stable Me3+, was formed and used. Particle efficiency was analyzed by TGA and XPS was used to analyze the oxidation state. XRD, SEM/EDS, and CV were used for analysis of other physicochemical properties. Thus, it was confirmed that sufficient oxygen transfer ability was obtained even if low cost particles were used.
