Effect of various reactor temperatures for mixed metallic oxides in chemical looping combustion system for carbon capture

Chemical looping combustion (CLC) is an innovative technology designed to address the growing concerns related to carbon dioxide (CO 2 ) 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 CO 2 while maintaining energy efficiency in power generation.The study of bubble hydrodynamics within the fuel reactor of a CH 4 -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 CH 4 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.
