Description:
Aiming to enhance the CO 2 capture capacity and the anti-attrition property of the CaO-based sorbents simultaneously, a novel CaO-based sphere was prepared by extrusion-spheronization method using Ca(OH) 2 powder with glucose templated. The CO 2 capture characteristics and attrition resistance property of the sorbent were examined and the microstructure of the sorbents was also analyzed. The results outline that the obtained spherical sorbents has outstanding anti-attrition performance compared to limestone sorbent. After 100 cycles, all of the templated sorbents hold a CO 2 capture capacity of over 0.18 g of CO 2 /g of sorbents, which was over one time higher than that of limestone. The optimum templating rate of glucose in the sorbent is 1-5 wt. %.
