dc.description.abstract | High-temperature CO2 sorption has been investigated as a new CO2 capture technology, and the development of high-temperature CO2 sorbents is critically important for the realization of this technology. In this study, K-Mg double salt-based sorbents were synthesized using a new pH-controlled precipitation method and the prepared sorbents were tested for medium high (intermediate) temperature CO2 sorption. In the new method for the synthesis of K-Mg double salt-based sorbents, the pH of the reagent solution was controlled by adding K2CO3 and/or KOH, resulting in varied ratios of different components in the sorbent. The CO2 sorption ability was enhanced in K-Mg double salt-based sorbents synthesized using the new pH-controlled method compared to the samples synthesized by the conventional precipitation method. The newly prepared K-Mg double salt-based sorbents had a high CO2 sorption uptake of up to 2.09 mol kg(-1) at 300 degrees C and 1 bar. In addition, they showed fast sorption kinetics and good cyclic stability during multiple sorption/desorption procedures. (C) 2016 Elsevier B.V. All rights reserved. | - |
