Abstract

Lithium orthosilicate based sorbents were prepared by solid-state method and impregnation-precipitation method, with SiO₂ as silicon source which was made from the waste residue of acid processing coal-kaolin. And lithium orthosilicate based sorbents doped with halloysite nanotubes exhibited excellent CO₂ absorption performance at 500-650℃, which were prepared by impregnation-precipitation method. The phase composition, morphologies and surface area were analyzed by XRD, SEM and N₂ adsorption-desorption isotherm,and CO₂ absorption performance was measured with a thermogravimetric analyzer. The results indicated that the absorption performance of Li₄SiO₄ made by impregnation-precipitation method, with small particles, particle size evenly distributed and large surface area, is better than Li₄SiO₄ made by solid method. And the maximum absorption capacity of lithium orthosilicate based sorbent made by impregnation-precipitation method reached 35.74% (704℃), corresponding to 97.33% efficiency. The absorption performance at 500℃ to 650℃ of sorbents can be improved greatly by doping aluminum with halloysite nanotubes. It was found that the sorbent got the best performance at 500℃ to 650℃ when x=1.04%, and the absorption capacity reached 12.78% at 540℃, which was 2.39 times as much as absorbent with non doping.
