Room-temperature ionic liquids (RTILs) have been found to induce precipitation of CO2-captured carbamate product in case of amine-RTIL systems that may lead to an efficient carbon dioxide capture process. Here we have studied the kinetic behavior of CO2 absorption in (mutually immiscible) DEA-[hmim][Tf2N] blends in a laboratory scale stirred-cell reactor at ambient pressure (similar to 1 atm) to assess the effects of amine concentration (<= 2 M DEA), CO2 partial pressure, agitation speed (1500-4500 rpm), and temperature variation (25-41 degrees C). A CO2 probe was used to monitor the change in gaseous CO2 volume ratio during the absorption experiments. (C) 2013 Elsevier B.V. All rights reserved.
