Abstract
Zeolite 4A was synthesized by fusion method from coal fly ash discharged at the thermal power plants. The synthesized zeolite(FAZ) was characterized through particle size analyzer, XRD, XRF and SEM. $N_2$ adsorption-desorption measurement was used to examine surface and pore structures. The adsorption experiments were carried out under dynamic conditions of trace $SO_2$ in $N_2$ to investigate $SO_2$ adsorption capacity of FAZ. The experiments were conducted to characterize the breakthrough characteristics of $SO_2$ in a fixed bed under different operating conditions including temperature(50-$125^{\circ}C$), concentration of $SO_2$(3000-10000 ppm) and FAZ with 4 kinds of commercial zeolite. The adsorption capacity of FAZ was 53.84 $mgSO_2/g$ adsorbent, larger than that of the same type commercial zeolite(WK4A).
