Description:
This study presents findings from an experimental investigation of the influences of several factors on the desulfurization activity of sorbents synthesized from coal fly ash, CaO, and CaSO"4. Specifically, the effects of specific surface area (16.1-133.3m^2/g), reaction temperature (60-300^oC), feed concentration of SO"2 (500-2500ppm), and feed concentration of NO (0-750ppm) were elucidated using a fixed bed reactor. In general, the sorbent desulfurization activity increased with increasing specific surface area, reaction temperature, and NO concentration but with decreasing SO"2 concentration. The physical and chemical properties of sorbent before and after SO"2 capture were characterized through scanning electron microscopy, X-ray diffraction, and Fourier transform infrared analyses.
