Potassium-based sediment sorbents have a better morphology with the surface area of 156.73 m2·g−1, the pore volume of 357.5×10−3 cm3·g−1 and the distribution of pore diameters about 2-20 nm. As a comparison, those of hexagonal potassium-based sorbents are only 2.83 m2g−1, 7.45×10−3 cm3g−1 and 1.72-5.4 nm, respectively. TGA analysis shows that the optimum final temperature of regeneration is 200 and the optimum loading is about 40%, with the best heating rate of 10 °C·min−1. By the modified Coats-Redfern integral method, the activation energy of 40% KHCO3 sorbents is 102.43 kJ·mol−1. The results obtained can be used as basic data for designing and operating CO2 capture process.
