The reaction kinetics of SO2 removal was studied by laboratory-scale experiments to examine the potential desulfurization efficiency by the waste cement particles. Desulfurization experiments for Ca(OH) 2 and calcium carbonate (CaCO3) were also conducted under the same conditions for comparison. Laboratory experimental studies showed that the waste cement particles have a sufficiently high reaction rate with gaseous SO2, under the temperature conditions of 30 - 400°C. The waste cement would be applicable for the desulfurization process, especially under the lower temperature conditions such as 30°C, under which the desulfurization rate is comparable with that of calcium hydroxide, which has been commonly used as a desulfurization agent but much more expensive than the waste cement. The use of waste cement would be a promising option for a dry desulfurization process.
