Abstract 

In this paper, the calcium-based sorbent was synthesized through the template method. The carbon sphere prepared by hydrothermal technique was selected as the template, followed by the hydrolysis of urea on the surface of the sphere. The morphology was characterized by scanning electron microscopy (SEM) and the cyclic adsorption performance of the sorbent at 600℃ was investigated by thermogravimetric analysis (TGA). The suitable hydrothermal time and the temperature for hydrolysis were 6 h and 80℃, respectively. The sorbent exhibited excellent performance with a high initial capacity of 74% and kept nearly unchanged for 15 cycles.
