Abstract: The concept of chemical looping reactions has been widely applied in chemical industries. Fundamental research on chemical looping reactions has also been applied to energy systems. Fossil fuel chemical looping applications were used with the steam-iron process for coal processing from the 1900s to the1940s and were demonstrated at a pilot scale with the HYGAS process and Carbon Dioxide Acceptor process in the 1970s. There are presently no chemical looping processes using carbonaceous fuels in commercial operation. Key factors that hampered the continued use of these earlier processes were the inadequacy of the recyclability and economic viability of the looping particles and their associated reactor system operation. With the CO₂ emission control now of great concern and the need for the development of high efficiency operational processes, interest in chemical looping technology has resurfaced for its unique ability in generating a sequestration-ready CO₂ stream with efficient and versatile process applications.

Chemical looping technology is a manifestation of the interplay among all the key elements of particle science and technology including particle synthesis, reactivity and mechanical properties, flow stability and contact mechanics, gas-solid reaction engineering and particulates system engineering. This presentation will describe the fundamental and applied aspects of modern chemical looping technology that utilizes fossil and other carbonaceous feedstock. Specifically, it will discuss the reaction chemistry, ionic diffusion mechanisms, metal oxide synthesis and thermodynamics, reactor configurations, and system engineering along with energy conversion efficiency and economics. The Coal-Direct Chemical Looping Process, STS Chemical Looping Process, and Syngas Chemical Looping Process being developed at Ohio State University at a pilot level will be illustrated. Further, the CO₂ emission control using the chemical looping technology will be compared with other CO₂ capture methods. Selective oxidation in the production of fuels and chemicals, solar based chemical looping technology and various process application options will also be discussed.
