| Résumé : | Flue gas desulfurization technology is important for coal-fueled power plants, and adsorptive separation of SO2 is a potential method applicable in practice. Large pore SBA-15 with surface modified by TEA (triethanolamine) showed excellent performance for the selective adsorption of SO2 from flue gas. The SO2 capacity reached 177 mg/g at 80% TEA loading ratio, while the adsorption of CO2 was negligible. The adsorbent also showed good tolerance to moisture existing in flue gas, and the moisture showed a positive effect on the desulfurization. The saturated adsorbent was regenerated when heated to 120 °C, and the SO2 capacity was almost retained in consecutive adsorption/regeneration cycles. |
