Coal-, oil-, and natural gas-fired power plants are the major contributors to anthropogenic emission of CO2. Therefore, it is necessary to develop technologies which can reduce CO2 emission while allowing us to utilize fossil fuels. However, commercial CO2 capture technologies including absorption by liquid media are not only energy intensive, but also have many operation restrictions. In this respect, development of highly efficient adsorbents with high adsorption capacity, high adsorption selectivity for CO2, and high regenerability are critical for the success of the PSA and TSA processes. The objective of this work is to investigate the performance of nano-structured metal oxide adsorbents in the CO2 capture, and to understand their adsorption-desorption mechanism on the basis of experimental and theoretical study.
