Abstract

The fly ash generated from the burning of low sulfur coals is featured by high alkalinity, which alone or mixed with CaCO₃ can be used as the absorbent for desulfurization. The desulfurization performance of fly ash and CaCO₃ compound absorbent is experimentally investigated in a bubbling desulfurization reactor. Results show that the desulfurization rate of CaCO₃ is improved by adding fly ash at Ca/S mole ratio of 1.024. The maximum desulfurization rate of the compound absorbent could reach 94%. The optimum ratio of fly ash and CaCO₃ in the compound absorbent is 1:1.
