| Abstract: | Desulfurization absorbent was prepared with fly ash and lime in the different conditions as hydration temperature, hydration time and lime/fly ash ratio. The surface properties of absorbent including surface area and pore size distribution were tested, and the desulfurization experiment was conducted on the fixed bed platform. Results showed that reasonable pore size distribution is helpful to desulfurization performance, and the surface area of optimum sample is 54.953m2/g. |
