Anthropogenic CO2 emissions produced from fossil fuel combustion are believed to contribute to undesired consequences in global climate. Major contributors towards CO2 emissions are fossil fuel-fired power plants for electricity production. For this reason, CO2 capture from flue gas streams together with permanent sequestration in geologic formations is being considered a viable solution towards mitigation of the major greenhouse gas1. Technologies based on chemical absorption with alkanolamines have been assessed for first generation CO2 post-combustion capture primarily due to its advanced stage of development. However, limitations associated with these chemical solvents (i.e., low CO2 loadings, amine degradation by oxygen, equipment corrosion) manifest themselves in high capital and operating costs with reduced thermal efficiencies. Therefore, necessary design and development of alternative, lower cost approaches for CO2 capture from coal-fired combustion streams are warranted.
