Chemical Looping Technology – A Particle Technology Perspective
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 from the 1900s to the1940s and were demonstrated at a pilot scale with the carbon dioxide acceptor process in the 1960s and 1970s. There are presently no chemical looping processes using carbonaceous fuels in commercial operation. A key factor that hampered the continued use of these earlier processes was the inadequacy of the reactivity and recyclability of the looping particles. This factor led to unsustainable operation of the process. With CO2 emission control now of great concern, interest in chemical looping technology has resurfaced due to their unique ability to generate a sequestration-ready CO2 stream.
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 design, and system engineering along with energy conversion efficiency and economics of the Coal-Direct Chemical Looping Process and Syngas Chemical Looping Process being developed at Ohio State University at a pilot level. Further, CO2 emission control using the chemical looping technology will be illustrated and compared with other CO2 capture methods. Potential for selective oxidation in the production of fuels and chemicals, as well as solar based chemical looping technology, will also be discussed.
Professor L.-S. Fan is Distinguished University Professor and C. John Easton Professor in Engineering in the Department of Chemical and Biomolecular Engineering at The Ohio State University. He has been on the faculty of Chemical Engineering at Ohio State since 1978 and served as Department Chair from 1994 – 2003. Professor Fan received his B.S. (1970) from National Taiwan University, and his M.S. (1973) and Ph.D. (1975) from West Virginia University, all in Chemical Engineering. In addition, he earned an M.S. (1978) in Statistics from Kansas State University.
Professor Fan’s expertise is in fluidization and multiphase flow, powder technology and energy and environmental reaction engineer¬ing. He is an inventor of 7 industrially viable clean fossil conversion processes : OSCAR, CARBONOX, PH Swing, CCR, Calcium Looping, Syngas and Coal-Direct Chemical Looping Processes. These processes control sulfur, nitrogen oxide and carbon dioxide emissions and convert carbonaceous fuels to hydrogen, electricity or liquid fuels. He also invented the electrical capacitance volume tomography for 3-dimensional, real time multiphase flow imaging that is currently being used in academia and industry. Professor Fan is the U.S. Editor of Powder Technology and has served as a consulting editor of ten other journals and book series, including the AIChE Journal, I&EC Research, and the International Journal of Multiphase Flow. He has authored or co-authored four books, 370 journal papers, and 39 patents.
Professor Fan has received a number of awards in recognition of his research and teaching including the ACS E. V. Murphree Award in Industrial and Engineering Chemistry, AIChE Alpha Chi Sigma Award for Chemical Engineering Research and R. H. Wilhelm Award in Chemical Reaction Engineering, ASEE Dow Lectureship Award in Chemical Engineering, CCR Malcolm Pruitt Award and The Ohio State University Charles E. MacQuigg Award for Outstanding Teaching and Joseph Sullivant Medal for Distinguished Teaching, Research and Service. He is a Fellow of the American Association for the Advancement of Science (AAAS) and the AIChE, a member of the U. S. National Academy of Engineering, a Corresponding Member of the Mexican Academy of Sciences, an Academician of Academia Sinica, and a Foreign Member of Chinese Academy of Engineering. Professor Fan was named in 2008 as one of the “One Hundred Engineers of the Modern Era” by the AIChE.
About Reuel Shinnar:
Professor Shinnar was a distinguished Professor of Chemical Engineering at City College, where he taught for 40 years and provided regular consultation to the oil and chemical industry, as well as for agencies including the US Department Of Energy and the Electric Power Research Institute. He was a member of the National Academy of Engineering and published over 100 papers in many areas of Chemical Engineering. His research has changed the design methodology of chemical processes, as well as their control. He was also an author or co-author of over thirty patents several of them in large-scale use. In fact the current Fischer-Tropsch process for diesel production being presently implemented by Shell, SASOL, and ExxonMobil relies on a patent of which he is a co-author; this patent drastically reduced the cost and improved the yield of the process. A lecture series in memory of Reuel Shinnar was established in 2012 by his friends and family, with the lectures held annually in the Department of Chemical Engineering at City College. The inaugural Shinnar Lecturer was Professor Manfred Morari of the ETH Zurich.
