Abstract

In this paper, one dimensional nanorod CaCO3 adsorbents were synthesized via hydrothermal method by varying the amount of polyacrylamide (PAM). The XRD results indicated that all of the characteristic peaks of synthesized adsorbents were matched well with the aragonite CaCO3 phase. FE-SEM analysis showed one dimensional nanorod structures with diameter of 40 - 70 nm and lengths up to micrometer. TG results exhibited CaCO3 adsorbents synthesized with 0.4 and 0.6 g of polyacrylamide possessed high CO2 adsorption capacities for first carbonation/calcination cycle (0.86 and 0.79 g-CO2/g-sorbent) which were higher than the theoretical CO2 adsorption capacity (0.78 g-CO2/g-sorbent) of calcium oxide based adsorbents.
