Chemical looping combustion for gaseous fuels: principles, oxygen carriers, and reactor design

The rise of industry is driving up global energy demand, and carbon footprint emissions have an enormous impact on the environment. The researcher is especially worried about the emissions of carbon dioxide brought on by growing industry. Chemical looping combustion (CLC) is a recently developed technology that employs metal oxides to burn fuel efficiently and simultaneously trap carbon dioxide. This method enhances energy consumption and dramatically minimizes the emission of greenhouse gas emissions, hence CLC can be a viable way for sustainable power generation and carbon capture in the face of low-carbon future. In another words CLC are recognized as a source of clean energy, and their optimal utilization reduces environmental impact. In this review article, we discuss the CLC principles, selection of oxygen carrier (OC), thermodynamics, kinetics, and process optimizations. Continued research and optimization of CLC reactor design, operating parameters, and OC materials are crucial to further improve the performance and facilitate the large-scale commercial deployment of this promising technology for sustainable power generation and industrial processes.
