Zeolite (FAZ) was synthesized by the fusion method using coal fly ash to adsorb sulfur dioxide[1].The experimental adsorption was operated batchwise in a laboratory-scale packed-bed adsorber to obtain the breakthrough curves of SO2 under the conditions,such as adsorption temperatures (50–150?C),flow rates of gaseous mixture of sulfur dioxide and nitrogen (50–130 cm3/min),and concentration of SO2 (1000–10000 ppmv) at atmospheric pressure of 101.3 kPa[2].The influences of gas flow rate,concentration of SO2 and adsorption temperature on adsorption behavior of SO2 were discussed.The experimental data of the breakthrough curves were fitted to the deactivation model(DM),which combined the rates of adsorption and deactivation to analyze the adsorption kinetics,using a nonlinear least squares technique[3,4].The adsorption isotherm,capacity,and heat of adsorption were prepared by DM using the breakthrough curve.The adsorptive activity and capacity of FAZ were larger than those of the commercial zeolite of Wako 4A.
