Abstract

Chemical Looping Combustion (CLC) is a next-generation combustion technology that offers inherent CO2 capture and high thermal efficiency. Despite its advantages, the risk of dust explosions caused by the mechanical degradation of oxygen carriers presents a major challenge in industrial-scale applications. This study aims to develop a regenerative oxygen carrier by combining iron oxide (Fe2O3) with magnesium oxide (MgO) using a co-precipitation method to enhance thermal and structural stability. Experimental analysis confirmed a high initial redox efficiency and reduced fine particle formation over multiple cycles. The engineered Fe2O3 – MgO carrier achieved a long-term efficiency of 81.7% after 10 cycles and exhibited strong explosion suppression potential. This paper highlights the material’s effectiveness in improving both performance and safety in CLC systems.
