Abstract

Chemical looping combustion (CLC) is an innovative technology designed to address the growing concerns related to carbon dioxide (CO2) emissions from fossil fuel-based power plants. As the world grapples with the challenges of climate change, the development of efficient and cost-effective carbon capture technologies has become imperative. CLC emerges as a promising solution, offering a unique approach to capturing CO2 while maintaining energy efficiency in power generation. The study of bubble hydrodynamics within the fuel reactor of a CH4–fueled CLC system has been incorporated into the present research work. The reaction kinetics have been incorporated into the reactive system of the fuel reactor by a user-defined function (UDF) during numerical analysis. The present study uses CuO and NiO as mixed oxygen carrier materials in various proportions and CH4 as a fuel in combustion processes. The various proportions of mixed metallic oxides have been considered as 30% CuO and 70% NiO, 50% CuO and 50% NiO, and 70% CuO and 30% NiO by volume. The bubble hydrodynamics in terms of development, growth, rise, and burst are visualized and analyzed in the solid-gas molar fraction inside the fuel reactor. In the recent work, authors have chosen different operating temperatures varying from 923 K to 1323 K. The fuel conversion rate has been observed to increase with the increased temperature.
