Designing Ionic Liquids for CO2 Capture
Ionic liquids present intriguing possibilities for removal of carbon dioxide from a wide variety of different gas mixtures, including post-combustion flue gas, pre-combustion gases, air, and raw natural gas streams. Even by physical absorption, many ILs provide sufficient selectivity over N2, O2, CH4 and other gases. However, when CO2 partial pressures are low, the incorporation of functional groups to chemically react with the CO2 can dramatically increase capacity, while maintaining or even enhancing selectivity. We will demonstrate five major advances in the development of ILs for CO2 capture applications. First, we will show how the reaction stoichiometry can be doubled over conventional aqueous amine solutions to reach one mole of CO2 per mole of IL by incorporating the amine on the anion. Second, we will show how we have been able to virtually eliminate any viscosity increase upon complexation of the IL with CO2, by using aprotic heterocyclic anions (AHA ILs) that eliminate the pervasive hydrogen bonding and salt bridge formation that is the origin of the viscosity increase. Third, we will show the advantage of phosphonium cations over their imidazolium counterparts. Fourth, we will elucidate the role water plays in both the reaction chemistry and the viscosity. Finally, we will discuss the role that the cation plays in the reaction chemistry.
Joan F. Brennecke is the Keating-Crawford Professor of Chemical Engineering at the University of Notre Dame and Director of the Center for Sustainable Energy at Notre Dame. She joined Notre Dame after completing her Ph.D. and M.S. (1989 and 1987) degrees at the University of Illinois at Urbana-Champaign and her B. S. at the University of Texas at Austin (1984).
Her research interests are primarily in the development of less environmentally harmful solvents. These include supercritical fluids and ionic liquids. In developing these solvents, Dr. Brennecke’s primary interests are in the measurement and modeling of thermodynamics, thermophysical properties, phase behavior and separations. Major awards include 2001 Ipatieff Prize from the American Chemical Society, the 2006 Professional Progress Award from the American Institute of Chemical Engineers, the J. M. Prausnitz Award at the Eleventh International Conference on Properties and Phase Equilibria in Greece in May, 2007, the 2008 Stieglitz Award from the American Chemical Society, the 2009 E. O. Lawrence Award from the U.S. Department of Energy, and the 2014 E. V. Murphree Award in Industrial and Engineering Chemistry from the American Chemical Society. She serves as Editor-in-Chief of the Journal of Chemical & Engineering Data. Her 120+ research publications have garnered over 10,000 citations. She was inducted into the National Academy of Engineering in 2012.
The Katz Award Lecture:
A special lecture by a distinguished expert is given each year in the memory of Professor Stanley Katz, who was a faculty member at CCNY from 1963 to 1971. Professor Katz was born in New York and was a graduate of CCNY in the Department of Mathematics. He later obtained a Ph.D. at the Courant Institute in New York. He worked for many years in the chemical industry, first at Hydrocarbon Research and later at American Cyanamid, as a mathematical consultant. He made significant contributions to chemical engineering literature, especially in optimization and control theory. He continued his research at CCNY and was admired and appreciated by his students and colleagues as a brilliant teacher and, above all, as a warm, wonderful human being. The Stanley Katz annual lecture is an unusual event made possible by the Stanley Katz Memorial Fund contributed to by his friends and colleagues.
